Fixed video video from breaking layout

When the screenn is less than 768 vimeo's iframe breaks the layout.

Also moved .valid & .error into the non-semantic helper classes section
instead of below the print styles. Fixed overflow.
Removed chrome=1 from X-UA-Compatibile meta

Due to Google Chrome Frame dropping support and being retired as of
February 25, 2014.
Merge remote-tracking branch 'upstream/master'
Added jquery local fall
Optimized some images
Merge pull request #14 from 06b/master
