Change subject: Groundwork for bottom sheets, part 2.
......................................................................
Groundwork for bottom sheets, part 2.
- Expanded our ExclusiveBottomSheetHandler to be able to support regular
Dialogs, not just DialogFragments (although Dialogs won't be saved in
the activity's savedInstanceState, but that's alright).
- Made a simple descendant of BottomSheetDialog that automatically
disables dimming of the background when it's shown, which we need for
some of our bottom sheets.
- Transitioned the ReferenceDialog, PageInfoDialog, and ShareDialog to be
BottomSheetDialogs, some without dimming.
- Goodbye, old "BottomDialog" class.
