Force the loading of all dependent JavaScript into the host application.

[mgurley]

Currently the gem requires jquery, jquery_ujs and jquery.ui.all in its own application.js. This should be the responsibility of the host application. Maybe there is something like bundler for JavaScript, but for now remove and add instructions that these items must be required within the application.js of the host application.

Discovered this because a host application was also requiring jquery_ujs in its own application.js and the double inclusion was causing remote forms to be submitted twice because of double binding of events.
