Use vim as a front-end to mpg123

vim-playlist requires a working python install. At the moment, it's tested against python 2.7. I hope to add 3.4 support soon. No additional libraries are required to run the server, although the tests do have a few extra requirements (mock, nose)

:PlaylistLoad path_to_playlist

The line of reasoning that has led me to this point can be summarized as:

1. iTunes sucks
2. So apparently does everything else
3. mpg123 is usable, mostly...
4. ...except the console controls aren't reading keyboard events right on my terminal, and frankly are pretty minimal anyway
5. The FIFO controls are working fine though
6. I should just write a script to manage the FIFO controls
7. It would be sweet if that script had a playlist editor
8. Even writing a minimal editor is a ton of work
