This resolved Task#18811: Cannot edit widgets in Firefox 21.0
http://squish.ish.com.au/tasks/18811
The edit and delete button were not visible becasue of .is(":hover")
in javascript which is no longer supported. Please do not merge untill next commit.
Made changes to widgets.js for  editing, deleting and loading
of newly added widgets without refreshing the page.
The widget edit fields appeared like images because the elements
were not being focused when clicked. Added a new event to javascript to focus
the elements when clicked.
Merge pull request #486 from ari/viks-can-not-edit-widgets-in-fireFox-21.0
