Adding vagrant file

so that I can develop this on my mac
gitignore the .vagrant folder

that relates to the currently running vagrant box, so it's specific
to each machine and is generated when you do vagrant up.
Added provision script for rvm

Right now it just installs rvm, nextup xmms2
Download and configure xmms2
I think the ruby paths are set up for xmms2
Got ruby to install successfully
Removed outdated todo comments
Added audio to the vm and alsa to the provision
Add the vagrant user to the audio group

So that they can play music.
Setup port forwarding for 3000

so you can access rails from the host machine
