Added an extra sword, using a new texture from the updated assets: Legends_Exalt_SwordGrey
Changed the Sniper's emissive and projectiles to reflect that they're supposed to fire psi projectiles.

fixed weapons turning 90 degrees when used.
increased the roughness scalar on the sword so it's not quite so reflective.

Added the correct Emissive masks
Added roughness to the DIF textures, removed the debug specular scaling.
>> although the sword might be a bit too shiny, may revert it in the future.
Swapped the meshes of the snipers to the darklance one, which is basically the same thing except higher quality.
This also fixes the floppyness for snipers, still looking into the issue on the other three.
