Fixed modalFooter Jade mixin submit visibilty toggle
Changed Requests page to single filter only
Major Scheduled/Request Refactor

- Combined Scheduled/Requests into one list due to cache limitations
and the fact that the security advantage was negated by the way SP
lookup lists work anyway
- Greatly simplified list structure/security
- Much better performance
- Greater reliance on JSON
- Added versioning in case there are rollbacks that must be made down
the road (collision/data corruption)
- Added TTMS field for Class # (needed by the J4 schedulers)
- Added host field to class request vs requestor name since the host
will already have the contact info and will help us determine TDY vs
local requests
- Changed open seats count to include pending seats to avoid
over-requesting seats
- Added open seats counter on build/edit class modal
- Added explain fields for all the seat counts on the right of the
course well (this doesn’t seem to be working right though).
