CustomPiOS 1.0.0

This is the first release of CustomPiOS and leaving of beta.

We didn't have versions until now because I was not sure how CusotmPiOS will look.

Now that both OctoPi, FullPageOS and others are releasing I thought its time to organise.

There is a master branch for stable released, and a devel branch for changes.

If you are using CustomPiOS branch just checkout the master of devel branch.
You might need to do

git fetch origin
git checkout master

or

git checkout devel

for newer stuff.
