* 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.

Use local imports instead given all relevant files are within the
same repository, and don't vary by configuraion.

* The notification-count style is only needed if you are logged
in. Given a small percentage of our users are logged in, we
load a lot of render blocking css unnecessarily.
* The bell icon is not needed for anonymous users so pull that
out from skins.minerva.icons.images which is loaded for all users
into a module only used by logged in users (skins.minerva.icons.loggedin)
* Simplify the user-button rule - it is overly specific - probably for
historic reasons.
Additional changes:
* Simplify isAuthenticated helper
