v0.7.98 - Major bug fixes

[0.7.97] - Events backend page - fixed bug with check/uncheck all
events. Monitor ID now passed to exportevents. Export events - fixed
broken placeholder image. Events now stored in /events/mid/eid. Admin
backend page - Add New Monitor reverted to using classic skin in a
colorbox for now. Fixed validation issues.
[0.7.98] - Major bug fix - If camera ID's weren't sequential things
would break. This was down to not checking the camera index was correct
but by assuming it was one less than the monitor ID itself. This has
been fixed and the system can now handle non-sequential camera ID's.
