Fix depth buffer texture (for soft particle shader effects)

thanks to

apparently the default doom3 texture filter was something using mipmaps,
which doesn't work so well for textures without mipmaps..
no idea why those two lines in idImage::CopyDepthbuffer() were commented
out, but they're needed (and also un-commented in TDM, I just missed
that when merging -_-)
