Some internal code and asset name changes. This should be the only time this happens.

-Huge 2d asset update. Still plenty of 2d assets to update, but this should eliminate pretty much all of the UI ugliness.
-Also added INI options to optionally disable Battle Rifles or Marksman Rifles from appearing, though this should be set before starting a new game or running Battle Rifle Pack for the first time.

Merged weapon and soldier animations for Conventional and Magnetic MR/BR from Skunkworks.

Updated the Conventional Battle Rifle to the Magnetic Sniper animation to prevent action cycling after each round.

Modified weapon attachment sockets to reduce clipping.

The Battle Rifle Pack now explicitly checks to see if the Conventional Battle Rifle and Marksman Rifle are in your base inventory on three occasions:

1. Starting a new campaign
   
2. Loading a save for the first time with the mod installed
   
3. Every time you load a save at the XCom base

Added support for ETC Weapons.
Added USE_AR_SCHEMATIC variable to config.
Slight modifications to Conventional BR and MR attachments.
Added custom archetypes for Conventional and Magnetic Marksman Rifles.

Added preliminary support for Grimy's Loot Mod.
