Title: Only load zen bg on button click

A split-up of the ill-fated https://github.com/ajaxorg/cloud9/pull/2493; part 2 of 3.

The zen background gets loaded whenever a new file is loaded. Essentially this means if you have files open, leave the IDE, and come back, the zen bg is downloaded. It's not a trivial thing as the background is pretty heavy. This now downloads the bg when the button is actually clicked
