Support for vagrant boxes python environments

[DamnWidget]

The main idea is be able to configure python interpreters that are installed and running in vagrant boxes using channeled SSH connections.

I came to this idea through the issue #51

First version of running remotes/vagrant guest machines is pushed on development branch. To make this work on vagrant environments some workaround and a checkout of the vagrant_server branch in the target guest machine is needed.

Some documentation about vagrant support has been added to the wiki on https://github.com/DamnWidget/anaconda/wiki/Vagrant-Environments but a lot more of documentation is needed, I will write more documentation and refactor the code tomorrow hopefully.

I am currently linting and autocompleting my development version of anaconda with a python interpreter running in a vagrant guest machine configured with public IP address, thats pretty amazing. I have to test forwarded and private yet but now is time to sleep.
