FIX: Popup errors when SCUD function is called via trigger

NEW: Support for CBRN and respirator masks to halve radiation damage to players - radiation damage is now reduced by 50% for players with supported masks, and another 50% for supported hazmat suits. Wearing BOTH a supported gas mask AND a radiation suit will reduce radation damage to ZERO. This feature is subject to further refinement and may be improved in the future.

Correction: Removed gasmask PBO's (they were added for testing) - functionality is the same; you must have the respective mod(s) loaded to use those gas masks...

NEW: Gas masks now reduce nuclear fallout damage by half when players are within the radiation hot zone. Support for gas masks from:
- BIS Contact
- Global Mobilization
- Hidden Identify Pack
- FAP Units
