[PATCH] Output AAC as M4A with metadata tags

Sometime before sending, Shevek typed (and on Friday 2011-04-01 sent):

I don't do perl, but with most languages, a test should be "=="
rather than "=". Is that the case here ? In which case the test
will be changeing the ext to "aac", returning true, and the main
command will then change it to "m4a".

Apologies if I'm barking up the wrong tree (there's a limit to
how many different languages one can learn at one time without
getting horribly confused :-)
