* 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.

progressive itself
A couple of tweaks to the form (padding) are made to preserve the form to
its previous glorious status, other than that the file remains the same.
