[Theora] libtheora-mmx-1.0alpha5 release

[j at thing.net]

Along with libtheora-1.0alpha5 this is a release of theora-mmx.
A drop in replacement that uses MMX assembly to speedup some of
the most demanding routines in theora encoding/decoding.
Right now it only works on 32bit x86 CPUs.

Thanks to everyone whose work made this release possible!
