Updated patch, this also adds the following functionality to ECLASS.cpp

After all the entity definitions are loaded a new function looks at each
eclass_t, if it has a "modelpath" set then it leaves it alone.	If it's not set
then it checks to see if a file called "sprites/<eclassname>.*" exists in the
vfs, and if it does exist then it sets the "modelpath" to
"sprites/<eclassname>.spr".

The result of this is, that to we don't have to modify and existing .def files
to use sprite model images,  you can now just drop any .tga, .bmp, .jpg, ,
.spr, into the fs_game's /sprites/ folder (e.g. quake3/baseq3/sprites/ or
halflife/valve/sprites/) and they will be used automatically!!
