Revise Create.js-related code when upstream issues have been fixed

As part of #1886566: Make WYSIWYG editors available for in-place editing, I worked on improving the naming of the different PropertyEditor widgets. Instead of:

Drupal.drupalContentEditableWidget

this:

DrupalEditEditor.direct

But then I ran into ridiculous problems because jQuery UI Widget works in ways that are completely beyond all common sense: http://stackoverflow.com/questions/7739525/jquery-ui-how-to-call-a-widge.... (namespaces aren't actually namespaces in jQuery UI Widgets.)

So I had to use "bridging" to be able to use namespaces:
jQuery.widget.bridge('DrupalEditEditor_direct', jQuery.DrupalEditEditor.direct);

Unfortunately, that breaks with Create.js: https://github.com/bergie/create/issues/166. Hence, that issue is now also listed in the issue summary.

#1979784: Factor Create.js and VIE.js out of the Edit module removed Create.js and VIE.js, so this was implicitly fixed there.
