Added unique LOBOT graphics for the vast majority of 1.13's firearms.
Also edited and re-rendered some of the existing LOBOT weapon graphics, in order to fix missing pixels (mainly thin barrels disappearing on some animation frames), and made wooden parts somewhat lighter for slightly better shading.
- XM25, OICW and AICS set to use the XM-25 graphics
- G11 and CAWS set to use the G11 graphics
-Added '25mm' to XM-25's descriptions, fixed several typos
* LOBOT: Add blood pools to most common death anims
* Move HasRifleInHand layerprop down in priority
Allows more specific graphics to take over precedence, eg. when a rifle instead of AR class weapon uses FAL graphics
