Patch by Hannes Domani

Contribs - FLAC: update to v1.2.1. Mingw32 patch is unneeded (upstream merge). A few bugs and crash are fixed, new support for all RIFF/AIFF metadata, including Broadcast Wave Format (BWF).

Contribs: Theora moves from alpha7 to alpha8. New encoder, one patch has gone upstream, and examples can be disabled. A lot of new features are available in the encoder. Postprocessing, anyone ?

Hmm, there is a security problem in this commit (cache file is world-readable).

Someone should fix this properly instead.

as it needs some specific processing in the decoder.
