Capistrano 3 compatibility

[etiennebarrie]

Doesn't work out of the box with Capistrano 3, for lack of Capistrano::Configuration.
Maybe a simple require is enough, but I think a review is necessary in regard of the large changes in Capistrano 3.

I had this same problem and took a stab at writing my own gem for Capistrano v3. The url is here if you want to give it a shot and shoot me some feedback. @etiennebarrie could you give my version a shot and let me know if it works for you?

great! I'll try to have a look
