ChromeVox: Add data for battery and rich text hotkeys to command store

This change adds metadata for the battery and rich text hotkeys so that
they appear in the ChromeVox menu, where the user can find details on
how to activate them. It also renames the commands so the internal
and external naming is consistent.
