Fix 'flash' issue (jquery-color.min.js is empty on cloudflare cdn)
Add a jQuery selector (reallyEmpty)
Allow a field to be optional
Set lab.project.catcphrase as optional
Rewrite animateHighlight. The old animateHighlight is now named flash, and the new one only change the bg color from the current color to a new one. (temporarily breaks the live edit feature)
Add the possibility to edit the empty elements, by adding them the 'editable' class
Make lab.project.catchphrase always editable
Add stop() before all animate()
