Draft

Hi!

I made a draft version for installing retrorig either from /usr/lib/RetroRig or a git cloned version. So far the installation runs more or less fault free, xbmc and RCB function, but xbmc's background is missing.

To test this,

* move ~/RetroRig and .retrorig to save locations
* `add-apt-repository -y ppa:beauman/retrorig-testing`
* `sudo apt-get update`
* `sudo apt-get install retrorig-setup`  (comes in with a handy 41MB)
* `sudo rm /etc/apt/sources.list.d/beauman-retrorig-testing-trusty.list*` 1)
* `sudo apt-get update`
* and `sudo retrorig-setup`. It will create `~/RetroRig`. 

OR you can run
* `git clone https://github.com/beaumanvienna/Retrorig`
* `cd RetroRig`
* `git checkout draft`
* `sudo ./retrorig-setup.sh`

See https://github.com/beaumanvienna/RetroRig/tree/draft and https://launchpad.net/~beauman/+archive/ubuntu/retrorig-testing.

Like I said, this is just a draft version. If this is not what you had in mind, I can just delete it. You don't even have to pull it in. It's meant to demonstrate what I had in mind with package retrorig-setup...

1) The new ppsspp version is segfaulting, that's why the test repro needs to be removed.
