Eliminate bbloom from namespace

Bumped version to 0.3.0-SNAPSHOT too.

I know that a lot of folks feel strongly that project names should be
qualified, but I disagree. I think that a decent project name is pretty
likely to be unique on its own and any conflict is best resolved on a
case by case basis. Furthermore, I dislike the extra folder in my
beautiful directory structure :-) However, I am going to miss the
branding benefits of having other folks see my name more often :-/
