Setup test and deploy chain

[funkenstrahlen]

Think about how to realize testing using travis - problem with mpd direct calls.

Setup deployment using https://github.com/progrium/dokku

Deployment via capistrano works now.

@HorstMumpitz Does dokku make sense if I already have capistrano deploment running?

TODO: travis auto testing.

I think Dokku makes a lot of sense. I just played around with it but it makes a very good impression. It is like your own little Github. Additionally it would be much easier to set up Staging und Live Server.

One thing wich has to be checked is the use of mpd with dokku. As it is a separated Docker container mpd has to be encapsulated in a different way.
