[theora] Remove the word "Alpha" from anywhere near Theora

[Ivo Emanuel Gonçalves]

Howdy,

I'm proposing to change the version state of Theora from Alpha to
Beta, or better yet to remove any mention that it isn't ready.  Theora
is ready.  Saying it's an Alpha version is cute in the eyes of a
developer who likes versioning numbers, but it's a nightmare in
regards to marketing.

Nobody wants to support something that's labeled Alpha.  Like it's
unstable and will explode and kill your puppie.  No, no.  Let's have
none of this anymore.

Do it on the next release.

Speaking of next release, when will it be?  That was one of the topics
in the last two monthly meetings and there was no feedback that I know
of.

Theora 1.0
