Reworked LW2 shotgun's stats to fit in with 1.1 changes.

Added LW2 compatibility.


For Long War 2, the weapons have been re-worked to basically be an improved variant of Conventional Weapons that take less time to make than laser weapons. They retain schematic squad upgrade functionality (on the basis that these weapons basically take Shen having enough supplies to make the machinery required to upgrade the existing firearms, rather than making new weapons wholesale), but have had their stats adjusted so laser weapons are still superior.

Buffed ETC Weapons to have magnetic tier shredding after playtesting it some more.

Added ETC Carbines as a SMG equivalent weapon, fixed ETC Shotguns not actually having a penalty for being used at maximum range.

Fixed ETC Shotgun schematic not having a tech requirement
