* Apply code conventions (mostly whitespace and missing semi-colons)
* Minor other nitpicks
-- '! important' -> '!important'
-- Ucfirst -> lc; for color names and keywords
-- Remove uses of system color keywords (they are deprecated) [1] Most had fixed fallbacks already. Using those now.
-- Remove version query string (foo.png?2), last modified in r66151. Now obsolete with ResourceLoader
-- 0px to 0 where possible
-- Remove commented out css rules and declarations without any comment (debug stuff like /*div{ border:1px solid Red !important;}*/)
-- Remove empty blocks ( .foo { } )
