Watermelon: projfix11a: 

1. Fixed a bug (I made some parenthesis order mistakes, near predictX and predictY, which might corrupt predictX, predictY)
2. Fixed a value corruption when predictX or predictY becomes negative, since proj_SendProjectile only expects UDWORD (now set them to 0 when they become negative, so the turret wont try to fire projectiles to some off-map coords)
3. Fixed zero height building bug (invincible rearm pads) when an imd's ymin is equal to ymax...
