Makerbot machines.xml

This is important and necessary.

After installing replicator-G and running it for the first time, a .replicatorg directory will be created in your home directory (without notification). You'll need to replace the machines.xml file in the secret ~/.replicatorg directory with the following code (or at least add in the part about Andy's Cupcake).

The machines.xml file describes how the machine is physically set up to replicator-G. The important difference between the Andy's version and the regular version is that Andy replaced the z-axis screws on his bot with better ones. The new screws are great for stability, but they have a different thread pitch from default, resulting in a different height traveled per rotation. The machines.xml file quantifies that travel for the build software.
