bitbucket forked version

[rismoney]

I forked the autostager, so that it now works with bitbucket...

The ruby bitbucket gem is not well maintained and hasn't kept up with an underlying api mess caught between v1/v2 supportability.

Anyway - I could easily integrate this new fork with the GH code here, but I believe at this point, it would be polluting this fine code base with conditionals and ugly rest calls, that "work on my version"

So I will open source the fork. I don't plan to push the gem under an alternate name, but instead provide local gem build/install instructions to anyone interested in rolling their own autostager for use on bitbucket and/or docker based bitbucket build.
