Begin work on the stylesheets.

Made 'banner' an id instead of a class, since there's only ever one per page.
Add "bourbon" gem to Gemfiles.
Add "jquery-ui.js" to the project instead of hotlinking from the JQuery site.

Developement was slow as fuck when I had to wait for the JQuery site to see each
presentation layout tweak!
Improve problem report submission and showing presentations.
Improve user creation, editing, and viewing presentations.
Many more improvements.

Show category, priority, etc. names instead of id numbers.

More links use the 'button' class.

Use bourbon's "em()" function to translate pixels to em units.
Should make zoom scaling better.

Admin's menu is now red, to make it clear that an admin is logged in.

Useless links removed, more links added to menu bar.

Secondary menu bar removed.

"(Admin)"/"(Unauth)" removed from layouts.
Refactor notice into layouts.
Import "bourbon" in each stylesheet.
Merge branch 'master' into presentation-master-merge
