Update/redesign/rename

So, seeing as the name mUbuntu is already taken by a couple of other projects, I decided a change was needed. I asked for some suggestions on the Ubuntu boards and none were forthcoming, so I just went with what I used for the address. So, welcome to the Ubuntu Music project! I also did a quick redesign so everything's not so squished up and I made some new artwork, so we've now got a proper logo and stuff. I created a couple of wallpapers based on the artwork, which I plan to use on any computers I use for his project. They can be found here and here.
