[glob2-devel] Turret behaviour improved

[Stephane Magnenat]

Hello,

Cyrille and I have improved turret behaviour. I also added commens to the 
code :-). Turrets now have priorities so that they first attack warriors, 
then explorers, then buildings. For a given type, the danger of the unit (the 
attack strength of warrior) and the probability to hit are taken into account 
to decide who is the target.

This breaks net game compatibility between CVS and alpha8, so I bumped net 
version number
