Mostly, this tries to move common logic up to the DiscussionPage as the
lowest common ancestor of these components sharing certain state.

It's still messy, though. :-/

-### Changes
-
-* Mithril
-    - See changes from v0.2.x @ https://mithril.js.org/migration-v02x.html
-    - Kept `m.prop` and `m.withAttr`
-    - Actual Promises are used now instead of `m.deferred`
-* Component
-    - Use new Mithril lifecycle hooks (`component.config` is gone)
-        - When implementing your own, you *must* call `super.<hook>(vnode)` to update `this.attrs`
-    - `component.render` now doesn't use the current state instance
-        - this is because of how Mithril v2 works
-        - now calls mithril on the component class (not instance) and its props
-* Translator
-    - Added `app.translator.transText`, automatically extracts text from `translator.trans` output
-* Utils
-    - Changed `computed` util to require multiple keys to be passed as an array
-    - `SubtreeRetainer` now has an `update` method instead of `retain`, and its output is used in `onbeforeupdate` lifecycle hook
-    - `Evented` util is now a class instead of an object
-    - `formatNumber` now uses `Number.prototype.toLocaleString` with the current application locale, and supports passing an options object (eg. for currency formatting - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/NumberFormat/resolvedOptions#Description)
-* Modals
-    - `app.modal.show` now takes the Modal _class_ (not instance) and optional props (`app.modal.show(ForgotPasswordModal, props)`)
-
-#### Forum
-* Forum Application
-    - Renamed to `Forum`
-    - `app.search` is no longer global, extend using `extend`
