ai: commander does some proximity demand checking when assigning soldiers to defense; effectively, calling reinforcements in a poorly defended friendly base now assigns the new soldiers to defend in that base, unless a player takes control of the soldiers
maps: fixed several map bugs
general: fixed crash at exit
items: sandbags made less responsive to impacts
items: fixed C4 key helper shown for other people's C4 when hovering over a deployed C4
balancing: impact grenades now make 80 damage (before 100), and normal hand grenade 30 (before 40). The HP of a jeep lower from 100 to 80. Sandbags now have 165 HP to sustain 2 impact grenade hits.
