common: use AlertState for Alert component data - pass this to AlertManager

app.alerts.show() now can take plain object OR AlertState instance - will return AlertState.prototype.key
app.alerts.dismiss() takes AlertState or state key (returned by show())

+### 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`
