* Update frontend to Mithril 2 - Update Mithril version to v2.0.4 - Add Typescript typings for Mithril - Rename "props" to "attrs"; "initProps" to "initAttrs"; "m.prop" to "m.stream"; "m.withAttr" to "utils/withAttr". - Use Mithril 2's new lifecycle hooks - SubtreeRetainer has been rewritten to be more useful for the new system - Utils for forcing page re-initializations have been added (force attr in links, setRouteWithForcedRefresh util) - Other mechanical changes, following the upgrade guide - Remove some of the custom stuff in our Component base class - Introduce "fragments" for non-components that control their own DOM - Remove Mithril patches, introduce a few new ones (route attrs in <a>; - Redesign AlertManagerState `show` with 3 overloads: `show(children)`, `show(attrs, children)`, `show(componentClass, attrs, children)` - The `affixedSidebar` util has been replaced with an `AffixedSidebar` component Challenges: - `children` and `tag` are now reserved, and can not be used as attr names - Behavior of links to current page changed in Mithril. If moving to a page that is handled by the same component, the page component WILL NOT be re-initialized by default. Additional code to keep track of the current url is needed (See IndexPage, DiscussionPage, and UserPage for examples) - Native Promise rejections are shown on console when not handled - Instances of components can no longer be stored. The state pattern should be used instead. Refs #1821.
