Respect the 'enable animations' pref when animating views.
Fix multi-select checkboxes
Hide settings menu in message view.

None of our settings is message related anyway.
Move message view theme setting from message view menu to global prefs
by default.

The message view theme isn't something the user is likely to change on a
regular basis, so we don't need to clutter the message view menu with
this setting. The menu item can still be enabled for those who want it.
Remove text selection menu item for JB and higher.

Those versions have text selection support built-in (via long pressing
the WebView).
Allow changing the message composer theme (background and text color).
