Bug 21608: Disable dropdown for found holds - add button to revert

This patch disables the dropdown for found holds, and adds a new button
to revert the waiting status, setting the hold to priority 1

Additionally we remove some changes from 19469 and update the JS to skip
found holds when updating priority

To test:
1 - Find a record with multiple items
2 - Place 4 holds (or more)
3 - Capture one ohld as waiting, one as in transit
4 - View the holds on the record - switch the last to priority one
5 - Waiting and transit statuses get confused
6 - Apply patch
7 - Observe dropdown is now disabled for waiting holds
8 - Confirm other holds operate as expected
9 - Confirm 'Revert found status' resets hold

Bug 21608: (follow-up) Use RevertWaitingStatus and do not alter _FixPriority

[EDIT]
Completely removed the changes to Reserves.pm by adding module prefix in
the request.pl script.
