WIP - can't get it working.
Updated gems.
Got it working!
Fix compiled JS errors.
Tweak sass-convert to return re-compiled CSS also.
Merge branch 'sass-convert'. Calling it baked!
Tweak Gist confirm dialog and use pushState() to change address on Gist save.
Restore /sass-convert route.

Returning compiled CSS along with sass-convert is redundant, the form is
auto-submitted when the Sass input is updated. Compiling CSS separately
is actually more efficient.
Renamed some methods, moved stuff around.
Bump Bourbon to 3.1.0
Merge remote-tracking branch 'upstream/master'
