Merging with Cake.Tfs

[pascalberger]

I've created a general purpose Cake addin Cake.Tfs with TFS related functionality (currently pull request retrieving and voting). Would you be interested in merging your functionality into the Cake.Tfs addin?

Sure thing. If you think this will add useful funcionality to that library, i am more than happy to contribute and merge.
