Account types at toplevel of Settings

Reorganized Account settings to show account types at the top-level
of Settings. Only account types that have accounts added are visible
here. There is an Add account button to add a new account.

Master sync toggle has moved to Data Usage screen in the overflow menu.
It shows additional detail of the function of the auto-sync toggle when
it is toggled by the user.

Account type screen (ManageAccountsSettings) shows list of accounts of
that type and any available authenticator settings. It additionally
verifies any Intents can be resolved before showing the corresponding
entry. This screen now shows last synced time for each account.

You can now sync all accounts of a type by selecting Sync now in the
Account type screen.

Account Sync screen that shows the list of syncable items has minor
tweaks:
 - "Last synced...", "Sync is OFF"
 - Doesn't show the authenticator settings here anymore.
