Revert "Simplify variables in compile-stylesheets"

This reverts commit f069acc1dad00797465ecc55d0e21109dfc218e0.

Commit f069acc1 changed the way that the Kuma root was detected in
compile-stylesheets so that output from Stylus would be less verbose.
The particular implementation, however, introduced a bug where the
script could not be run from within its own directory. As it turns out,
there is no easy, portable way to do what commit f069acc1 intended.

Fix Bug #1032058 - Translation Form Alignment

1. Fix the expand and collapse widget so that the icons signalling functionality display.
2. Move the page meta information into its own expanding and collapsing area (the only meta information right now is tags).
3. Move the remaining information to fill the width of the page instead of being underneath the translation side.
4. Title this new section "version notes" (it's called version comments in the screenshot but I didn't like that).
5. Fix attachments so they show up again.
6. Document heiracrchy fixes to support new organization.
7. Style fixes for page-button alignment.
8. Move Review Flags up in document order.

Potential site wide impact:
- changed behaviour of clearfix() to clear using clear:both instead of :before
- removed wiki-block as extend for page-tags and page-comments and instead placed the class on the blocks.
