#### Is this adding or improving a _feature_ or fixing a _bug_?
Improvement / debt.
#### What's the new behavior?
This pull request removes the `Change` object as we know it, and folds all of its behaviors into the new `Editor` controller instead, simplifying a lot of the confusion around what is a "change vs. editor" and when to use which. It makes the standard API a **lot** nicer to use I think.
---
###### NEW
**The `editor.command` and `editor.query` methods can take functions.** Previously they only accepted a `type` string and would look up the command or query by type. Now, they also accept a custom function. This is helpful for plugin authors, who want to accept a "command option", since it gives users more flexibility to write one-off commands or queries. For example a plugin could be passed either:
```js
Hotkey({
hotkey: 'cmd+b',
command: 'addBoldMark',
})
```
Or a custom command function:
```js
Hotkey({
hotkey: 'cmd+b',
command: editor => editor.addBoldMark().moveToEnd()
})
```
###### BREAKING
**The `Change` object has been removed.** The `Change` object as we know it previously has been removed, and all of its behaviors have been folded into the `Editor` controller. This includes the top-level commands and queries methods, as well as methods like `applyOperation` and `normalize`. _All places that used to receive `change` now receive `editor`, which is API equivalent._
**Changes are now flushed to `onChange` asynchronously.** Previously this was done synchronously, which resulted in some strange race conditions in React environments. Now they will always be flushed asynchronously, just like `setState`.
**The `render*` and `decorate*` middleware signatures have changed!** Previously the `render*` and `decorate*` middleware was passed `(props, next)`. However now, for consistency with the other middleware they are all passed `(props, editor, next)`. This way, all middleware always receive `editor` and `next` as their final two arguments.
**The `normalize*` and `validate*` middleware signatures have changed!** Previously the `normalize*` and `validate*` middleware was passed `(node, next)`. However now, for consistency with the other middleware they are all passed `(node, editor, next)`. This way, all middleware always receive `editor` and `next` as their final two arguments.
**The `editor.event` method has been removed.** Previously this is what you'd use when writing tests to simulate events being fired—which were slightly different to other running other middleware. With the simplification to the editor and to the newly-consistent middleware signatures, you can now use `editor.run` directly to simulate events:
```js
editor.run('onKeyDown', { key: 'Tab', ... })
```
###### DEPRECATED
**The `editor.change` method is deprecated.** With the removal of the `Change` object, there's no need anymore to create the small closures with `editor.change()`. Instead you can directly invoke commands on the editor in series, and all of the changes will be emitted asynchronously on the next tick.
```js
editor
.insertText('word')
.moveFocusForward(10)
.addMark('bold')
```
**The `applyOperations` method is deprecated.** Instead you can loop a set of operations and apply each one using `applyOperation`. This is to reduce the number of methods exposed on the `Editor` to keep it simpler.
**The `change.call` method is deprecated.** Previously this was used to call a one-off function as a change method. Now this behavior is equivalent to calling `editor.command(fn)` instead.

#### 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 ability to click multiple emojis
currently, after clicking one emoji, user needs to click in the editor before being able to add another emoji
this fixes that by jumping to next text block and focusing selection to make it obvious where next insertion will take place.
* lint code
* 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
* 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
