Beta at last!

I think pyb00st is useful enough to be considered 'beta'.
I still have to document it better but this Line Follower robot is a good example of how what is already possible to do with it:

Almost beta

Still need to make some tests but I think it's pretty much close to beta release.
Keeping alpha because some variables need a better name.
Hope in less than a week to complete.
