New DCA/DP flow including git-tfs

Hi Team, maybe it is useful for some other project that have to use Git and TFS together.

@matiasbeckerle, @gkolocsar, @gastonmancini. @jfazzini it is the updated flow to use Git in our projects, it is a simplified version of our previous flow.
I am dealing with format (and also migration to kramdown) in a separated branch, I am also trying it against http://andresmoschini.github.io/makingsense.github.io so, probably it is a little unestable. Please, do not worry about format yet, there will be a new pull request related.
