done.  i used Steve's loadDummyTexture() in the event that
make_mip_maps() finds non power-of-two sizes.

while i was at it, i added some simple error message routines:

	void ssgSetError(const char *fmt, ...);
	char* ssgGetError(void);
	void ssgClearError(void);

this is similar to what SDL uses.  SetError fprintfs to stderr
and stores the message in a buffer that can be retreived with
GetError.  SetError could also echo to a stderr.txt file if
we want to capture multiple error messages.

I'd like to apply these error message routines to my loaders
and perhaps all of SSG unless there are objections.
