Fix for issue #200 on git. Pages in communities should only lock when they're set to lock in the `community_type_pages` table now.
Updated public (student) gradebook view to include the median grade if enabled in the settings file.
Added check to ensure $entry_ids is set before instantiating a foreach using that variable.
Updated clerkship sidebar search to use the same results page as the index page search does, as the old one it was pointing to had some less useful interfaces it was pointing to, which didn't include event titles, or the clerk progress and logbook entries.
Clarified the Mean/Median marks column titles, as well as adding "Your" to the Mark column.
