* Rename "More Options" back to "Options" (distinguisher no longer
  necessary).
* Update in-progress title to "Translating...".
* Update done title to "Translated".
* Show "Options" menu from done panel.
* Move "Always translate" checkbox inside advanced panel.
* Remove "Language settings" link from advanced panel (not slated for
  updated UI either).
* Update "never" options to state "Don't translate X" instead of "Never
  translate X".

Also replaces the views::MenuButton with a Harmony-compliant bubble and
updates the option menu on every click so any language changes done
inside the advanced panel are reflected in the menu outside.
