Option to show percentage charge in the icon
Summary:
add an option to show a text label with the percentage value
in the battery icon. text will be shown bottom-right
of the icon with a background for readability, similar to
unread count for IM or email apps.
code was already there but effectively dead code
Test Plan: tried both with and without label
