Removed the ability for shared teachers with grading privilege to see
student names in the grading tool.
Added some improvements to the idea basket such as changing the 'Copy'
button text to 'Copied' after the student copies a public idea, added a
'Times Copied' column, added an 'Origin' column, and no longer refresh
the idea basket UI after copying a public idea.
Fixed a bug where the insert media dialog was opening behind the step authoring window

- Was caused by jQuery UI 1.10 update which removed the zIndex dialog option
