Use stb_image for retexturing support, also support png, no more libjpeg

Browse source 
Retexturing support is now always on (you can still switch it off with
the gl_retexturing  CVAR), as we don't have the additional libjpeg
dependency anymore.

stb_image is used for tga, jpg and the newly supported png, so the
old tga and jpeg loading code has been removed.

I furthermore cleaned up the somehow messy and possibly slightly broken
retexturing selection code in R_FindImage()
