#### Is this adding or improving a _feature_ or fixing a _bug_?
Debt.
#### What's the new behavior?
This removes almost all existing deprecations from previous API changes, to save on filesize and reduce complexity in the codebase going forward.
It also changes from using the `slate-dev-logger` to using the Facebook-inspired `slate-dev-warning` which can be compiled out of production builds with [`babel-plugin-dev-expression`](https://github.com/4Catalyzer/babel-plugin-dev-expression) to save even further on file size.
The only deprecations it keeps are in the `fromJSON` methods for data model changes like `.kind` and `.leaves` which may still may not have been migrated in databases, since this is a bigger pain point.
#### Have you checked that...?
* [x] The new code matches the existing patterns and styles.
* [x] The tests pass with `yarn test`.
* [x] The linter passes with `yarn lint`. (Fix errors with `yarn prettier`.)
* [x] The relevant examples still work. (Run examples with `yarn watch`.)
#### Does this fix any issues or need any specific reviewers?
Fixes: #1922Fixes: #2105Fixes: #646Fixes: #2109Fixes: #2107Fixes: #2018
* Add Prettier, with basic config and ESLint integration
* Apply Prettier to all files using `yarn lint --fix`
* Tell Prettier to ignore an empty text in a test output.
* Run Prettier on JS files not handled by ESLint, and lint them too
* Implement first working rollup config for main slate pkg
* Convert slate-base64-serializer to rollup
* Convert slate-dev-logger to rollup
* Convert slate-html-serializer to rollup
* Convert slate-hyperscript to rollup

* Add plugin to replace process.env.NODE_ENV
* Only rebuild modules and dev examples in watch mode
* Enable sourcemaps for development builds
* Force debug to use browser version, remove builtins plugin
* Remove is-image from example
It relies on node `path` and wouldn't work well in-browser anyway

* Move stray require to import
* Configure examples to watch child package output
* Fix tests
* Remove unneeded preferBuiltins from resolve config
* Use more precise files array to ensure sourcemaps aren't included
* Use lodash instead of lodash.throttle
It's pulled in anyway since slate-react needs slate, so using the
minipackage actually causes code duplication

* Add rollup configs to linting, add a missing dep to package.json
* Use longform rollup CLI flags
* Add rollup-plugin-auto-external to reduce external module configuration

* Centralize to a single rollup configuration
* Update dist structure and package field naming for PR feedback
* Add comments and address PR feedback on rollup config
* i.e. -> e.g.
* Add some spacing to the configuration to improve readability
* Add a bit more spacing
* Remove umd from example Slate unpkg link
* added export constant enum for schema violations
* updated examples to use the schema violations enum
* use SchemaViolations enum in tests and docs
* fixed path for schema violations import
* rename state to value in slate core, as deprecation
* rename all references to state to value in slate core
* migrate slate-base64-serializer
* migrate slate-html-serializer
* migrate slate-hyperscript
* migrate slate-plain-serializer
* migrate slate-prop-types
* migrate slate-simulator
* fix change.setState compat
* deprecate references to state in slate-react
* remove all references to state in slate-react
* remove `value` and `schema` from props to all components

* update guides
* update reference
* remove data from event handler signatures
* standardize known transfer types
* add setEventTransfer to docs
* update examples, fix drag/drop
* fix tests and draggable attribute setting
* Make sure nodes update when their selection change
(cherry picked from commit 3e8744409ea94554faafa1e72415cdfb54b4bc78)
* Update examples of showing selected blocks nodes
* refactor to extract applyOperation util
* change handlers to receive transform instead of state
* change onChange to receive a transform, update rich-text example
* fix stack iterationg, convert check-list example
* convert code-highlighting, embeds, emojis examples
* change operations to use full paths, not indexes
* switch split and join to be recursive
* fix linter
* fix onChange calls
* make all operations invertable, add src/operations/* logic
* rename "join" to "merge"
* remove .length property of nodes
* fix node.getFragmentAtRange logic
* convert remaining examples, fix existing changes
* fix .apply() calls and tests
* change setSave and setIsNative transforms
* fix insert_text operations to include marks always
* cleanup and fixes
* fix node inheritance
* fix core onCut handler
* skip constructor in node inheritance
* cleanup
* change updateDescendant to updateNode
* add and update docs
* eliminate need for .apply(), change history to mutable
* add missing file
* add deprecation support to Transform objects
* rename "transform" to "change"
* update benchmark
* add deprecation util to logger
* update transform isNative attr
* fix remaining warn use
* simplify history checkpointing logic
* fix tests
* revert history to being immutable
* fix history
* fix normalize
* fix syntax error from merge
* Fix getFragmentAtRange to not return early when selection is in void node or collapsed
* Detecting when cut or copy is made in a void node, and not returning early
* Checking if text exists before using it for cut/copy
* Moving inVoidNode check to onCutOrCopy
as per @ianstormtaylor note.
* If/else for dom operations when copying text vs void node
* Adding fragment span to the contents
* more work on copy-pasting void nodes
* refactor Selection, deprecating old methods
* fix a few more things
* introduce an alternative for moveToOffsets
* add edge methods for move{start/end}OffsetTo
* fix selection return value
* fix deprecation warnings
* refactor transforms to make auto-generating easier
* refactor and deprecate selection transforms
* remove deprecation warnings from tests
* fix deprecation warnings in examples
As void-nodes now can be deleted, use a schema rule to normalize the document, and insert a paragraph when empty. Delete old "onDocumentChange" handler.
