Updated to current version 0.1.0

* Fixed the stupid mistake in the last build that gave you an
IndexOutOfBounds Exception.
* Fixed a bug where anyone who got onto the Launch Unit got double the
money (not bad).
* Added test classes. At least I think so. I hope this is what Carlton
meant by asking for test classes. We'll see.
* A few changes in the variables, mainly trying to make classes more
independent and future changes simpler.
