Added USB MIDI code

I’ve just uploaded the code for my first USB project to Github and updated the project page. :)

USB MIDI Controller

I recently started learning to play the electric guitar. To be able to spend more money on the actual guitar, I forwent to buy an amp and chose instead to use Guitarix, an open source program that can do all sorts of nifty guitar effects. It also has MIDI support, meaning that you can use hardware that speaks MIDI to control it, e.g. a slider or foot pedal. The cheapest pedal I could find went for 45 EUR on eBay, so I decided to build my own.
