Support for sprites was added to libiff.

Support for SPR# and SPR2 was added to iff2html.

*NOTE: The default exporter used is the PNG one, since web browsers
don't like targa. However, since there is a bug in my PNG exporter, I would
recommend that you use the targa exporter for a precise representation of the
loaded sprite frame(s). Feel free to fix the PNG exporter, btw :)
