- changing Assimp's coordinate system from RH z-up to RH y-up
 - fixing coordinate system for LWO, 3DS, ASE, MD5, MDL, B3D, IRR, IRRMESH 
 - converttolh moved to three separate steps -> flipuv, flipwinding, makelh

LWO 
 - fixing texture coordinate generation -> mapping axis is correct now 
 - fixing z-fighting bug

ASE 
 - fixing crash due to invalid normal setup 
 - fixing parenting bug 
 - code cleanup

IRR 
 - code cleanup
 - fixing placement of externally loaded meshes 

MDL 
 - fixing texture coordinate space

PLY 
 - cleanup 
 - two-sided maat property is now set
