Log Message:
Added a license file for lame based on many notes from different
files in the lame source.

And for the audio/lame/Makefile:

Change the LICENSE from fee-based-commercial-use to use this new
lame-license.

The problem before was that fee-based-commercial-use did not exist
and the "make show-license" suggested running pkg_info -d to view
the long-description of the package (which may not be installed yet).
Anyways, the DESCR didn't mention these license issues.

Also bump PKGREVISION.
