opusfile version 0.2

This is the second release of libopusfile. Like libvorbisfile for
Vorbis files, libopusfile provides a high-level API for decoding
and seeking within .opus files.

Changes since the previous release:

- Accept valid SSL certificates.
- Various build and packaging fixes.

The library is functional, but there are likely issues
we didn't find in our own testing. Please give feedback
in #opus on irc.freenode.net or at opus@xiph.org.
