-Small fix Anti-air

- Artillery designer added. Now you can create your own artillery.
This designer was created to unload the interface for the production of equipment, as NSB did with tanks, now there is a base carriage on which one or another weapon is installed, converting artillery into anti-tank or air defense.
The approach to rocket artillery has also been changed, since at a basic level, rocket artillery performs the same function as conventional artillery, so rocket artillery has become a separate module for artillery and rocket artillery has been removed from the division editor.
- Fixed OP with flamethrowers.
- Cut down and rebalanced many modules of infantry equipment.
- Added separations for special infantry equipment modules.

I fucked the paradoxical AI_equipment, so I tried to write an alternative AI based on on_actions, now the AI will hopefully create new equipment with modules. Performance can drops at the end of the month
