Bitbucket.org / Bitbucket Server first class support

[deldrid1]

@ppetrosh - My organization uses BitBucket Server as an internal, private git repository host.

Any chance Bitbucket Server (and therefore bitbucket.org) could have first class support like Github? https://www.npmjs.com/package/bitbucket-server-nodejs looks pretty similair to what is being used by /src/Readers/GithubReader.js... :)

This makes sense, will look into it.

Also, whenever this comes to fruition, if NO_PROXY support could be added in addition to the HTTP(S)_PROXY variables, that would be very handy :)
