- Extracted the loader
- Extracted ViewType and introduced WidgetView.
WidgetView is ViewType + mutable fields, such as account id.
WidgetView now owns the method to switch views.
These two are basically in preparation to address the message count bug.
(we're showing total message count where it should be the unread count,
which is a bit tricky because it'll require two different queries.)
- Also simplified the threading model in EmailWidget to fix potential
theading issues. (now (almost) everything works on the UI thread)
