[theora] libtheora-1.0alpha7 release

[Ralph Giles]

All,

I've done a new alpha release of the libtheora reference implementation. 
This is mostly build fixes from the alpha6 release; I'd failed to enable 
the new MMX asm by default, and the x86 asm code did a relocation that 
caused problems on SELinux.

You can get it in the usual place:
