- Don't use the action bar spinner.
Instead use a custom view to show the current account.
(It's not a spinner; now we show the dropdown list by ourselves,
which gives us more detailed control.)
- Also show the current mailbox name/unread count with the account name.
- Removed the mailbox info loader in ABC.
Instead, now the AccountSelectorAdapter loader loads the current
account/mailbox name, and the unread count as extras.
- Now ABC.Callback.onMailboxSelected passed an account ID as well
as a mailbox ID.
- There's new code paths that can cause the "fragment transaction in
onLoadFinished" exception. We need to fix this properly, but
for now we just use commitAllowingStateLoss().
