- OVERKILL prompt placed later in the scripting to avoid bllack-screen glitch

- Enemy helicopter now pathfinds correctly
- The 3 Deltas are now only given as a reward for the relay; in return for the increased difficulty, it will also give 2 more Rangers.
- Added a few supply dumps around the map based on player feedback
- Added new OVERKILL difficulty if already playing on Hard & reworked scripting to accomodate the changes. Existing difficulties remain the same. Extremely difficult!!

Fixed some scripting errors
