Anti air turrets have been added as a new kind of turret. You can create them by doing /turret antiair (now permission based)
default permissions changed, they are now rocketturrets.rocket & rocketturrets.antiair
Anti air turrets shoot heat seeking rockets that will seek a helicopter
Added configurable damage amount done to the heli
Updated the /turret menu, options for upgrades will only show if you have the correct permissions. (this also includes a language file update, so make sure to generate a new language file)
