Fixing bug #136 and #150: Giving admins option to disapprove a fingering when it has been submitted. Changing disapproval to actually deleting the fingering as discussed with Susan (dialog is displayed to confirm that the admin would like to do this). Also updated any generalized dialog confirmation messages (such as ones that just said 'Are you sure?') to being more specific/detailed. Made all messages specify what action would take place if confirmed.
Adding feature for bug #158. Users can now filter search results by keytype (std, alt, both) before beginning the search.
Merge pull request #156 from uidaho-bsn/ryan-dev
