AIFF/AIFC support! Based on Monty's old ogg application.
Probably pretty limited, but it seems to work. My only test file was what sox
output. AIFC is completely untested, actually.

A bugfix or two elsewhere, as well (compiling with -Wall is highly recommended)
And a new version number (mentioning beta4, so that official beta4 builds will
actually say that.)
