Deprecate pbiggar/trychooser and point people to https://bitbucket.org/sfink/trychooser

I don't think it makes sense to have users split between two trychooser forks which means updating both in parallel. sfink's fork improved on pbiggar's and is also maintained so I think we should deprecate this version and point people to https://bitbucket.org/sfink/trychooser from this extension and in documentation. Thoughts?

A good thing to do, but hold off on the execution until https://bugzilla.mozilla.org/show_bug.cgi?id=974224 moves it into hg.m.o so it's a one step pointer instead of pointing to a bitbucket pointer to hg.m.o.

Yeah, good point. I was thinking about that new repo but then forgot about it when I wrote the comment.
