1. Rebuild the heathchecked-resource component now we can copy and paste
2. As the above rebuild came with new icons, we also swapped out 'most'
of the other areas where we were using these new icons, plus any icons
that were effected by the new icon placeholders
3. Begin to remove more and more of the project specific icons (now
replaced by the shared ones)
* Begin refactoring CSS into component folders. Moved most
components into layout/skin folders, left out a couple of ones I want
to think about more.
* Adjust grays based on recent Structure changes
* Switch to fullscreen layout for lists and detail, left aligned forms (#4435)
* Specifically use the 'actions_close' label, not just the :last-child (actions-group)
* Replace some non-var-ed colours in vaults code skin, plus prefixing (black and white)
