Missing group library settings causes JS aggregation to break Ajax

An updated patch which includes the JS files in the libraries group, adds the debounce library as a dependency of the displace library (which could result in the libraries being added to the page in the wrong order) and skips the default CSS grouping (as the CSS files should receive that grouping automatically).

Tested #3 and committed to Dialog 7.x-2.x.

Automatically closed - issue fixed for 2 weeks with no activity.
