Bat swarm, slice, Mob Projector updates

- Bat swarm defense is completely revamped and updated - Slice skill is improved, see updated help. Reminder: samurai's parry can also cause this effect. - Clerics and druids can regrow sliced parts (thanks, Evengard), paladins can get that as a miracle via lay hands (thanks, Todomori). Also available for 1200 gold from city healers. - Enhanced armor now works correctly vs. thrown weapons -- very rarely though - All skills and spells now render character prone (drop on the ground) the same way -- with same chance factors and same limitations. All wait states caused by falling prone are also standardized. - Updated lots and lots of NPC offensive skills around the world -- creatures who aren't supposed to disarm, dodge etc. won't do that anymore. If you see something suspicious -- bugreport it! - Many creatures who shouldn't pick up stuff from the ground won't do that - Many savage beasts who are supposed to tear corpses to shreds will now do that - Updated many other NPC body parts and form flags around the world - Fly (flydown, flyup) commands are improved, minor bugs fixed (thanks, Rover) - Samurai misogi skill is fixed and updated - Affects command now has a few helpful synonyms (thanks, Nimly)

Don't forget to read all the updated help articles. Thanks everyone who reported bugs and typos!
