New feature: delayed grenade explosions:

- use transformation menu to change explosion mode
- only Normal/Stun/Flashbang type grenades can be delayed
- AI soldiers will avoid staying close to armed grenades\explosives
- use option DELAYED_GRENADE_EXPLOSION to make all hand\GL grenades work as delayed
- new value AP_GRENADE_MODE = 4 in APBPConstants.ini
- new item flag DELAYED_GRENADE_EXPLOSION

Other changes:
- fixed call to sqrt in DrawExplosionWarning() that prevented compiling in VS2010
- correctly update interface after transformations
- PATHAI: AI soldiers will skip gassed tiles if not in gas already
- InGas check: AI soldiers will avoid mustard gas even when wearing gas mask
- Yellow AI: added check to avoid gas/water/bomb using FindNearestUngassedLand
- gas/flare grenades will always explode instantly even when in bad state
- LegalNPCDestination: locations near armed bombs are not legal
- FindBestNearbyCover: avoid locations near armed bombs
