* Remove ambiguity in imports - say the file extension
'less' for all instances of variables and mixins.
* Separate toast styles from drawer styles so they can be
imported separately
* associate header-action selector with its parent
(.overlay-header) not parent's parent (.overlay) so it can be imported
and rendered without the Overlay.

In I629245100f4ca430a88e450939b90d075e7021f1, languageOverlay styles and
LanguageSearcher styles were split into two different files. This commit
mimics that change in skinStyles. All languageOverlay specific styles
were moved to languageOverlay.less, while all LanguageSearcher styles
were moved to LanguageSearcher.less.
