Fairly simple reports changes, and clerkship fix

Previously, the evaluation reports (course and teacher in particular) allowed you to hide the comments with a checkbox (well, many) on the left side of the page. It was requested here at Queen's to allow users to also be able to hide the evaluation target name and the numeric data. So, while doing that- I changed it to have only one sidebar instead of many, as it was operating as though it was only one before anyways, and made the evaluator target name show blacked out boxes (think redacted information) where the evaluation target's name would show previously.

Additionally, there was some strange behaviour going on with the clerkship student search functionality based on the way the string were being compared, so I fixed that, and removed the unused search action from the module, as it is handled by the index for both the admin and public clerkship modules now.
