fixed nav mesh bug that caused wiped teams on Grave_Discovery to respawn at the end Safe Room

New Map Added!
Grave Discovery is map 2 in the campaign and is now included. Potentially more to follow.
For the moment the gauntlet ending isn't working. Will correct this soon but the map is still playable and fun.

Item placement reworked - less healthpacks and explodables to make things more challenging. Reworked items to allow for better flow with map 2 now included.
Rarer items are now rarer
Ammo piles less frequent (the director seems to love Ammo piles!?)

Some visual tweeks to map 1 and 3.
Hints added and corrected.

Hope the added length addresses some of the issues some were raising.

Reworked Nav mesh and corrected lots of problems.
Added some clipping.

Added rescue closet.. ooops!

added a gnome you can steal in the finale
