File tweaks.

Reverted the cost change of the heavy turret. 12 components was way too much, I forgot autocannons had a component cost of 9.
Removed debug logging from the tree interception rework.

Heavy turrets are now 2x1 instead of 1x1. They also cost more components.
Any heavy turrets in existing saves will harmlessly minify themselves.

Patched the Highfleet Turrets mod.

Minor code improvements.

Reworked arrow-related patches to be a lot more modular. Now, all crossbow and greatbow projectiles should automatically revert to dropping arrows.

Reintroduced the assault shield from Combat Extended Armory.

Applied the cannon cost tweaks to the warcasket handheld cannon as well.

Cannons from VFE - Pirates are now more expensive and require reinforced barrels to craft.

The bombardier turret is now stuffable.
