Altering the Marlin firmware for the Lowrider2 CNC

This is a work in progress. I'll only be focusing on the Mini Rambo board as this is what I currently have. I'm merely sharing my configuration if anyone sees any use for it.

Current changes list:

• Removed extruder temp display on status screen
• Removed fan icon
• Removed temperatures menu item
• Arranged for the XYZ coordinates to take over the top part of the status screen
• Moved auto home menu item 3 spaces below the motion menu to avoid accidental triggering
• Added custom gcodes to engage and disengage the axis separately and altogether
• Enabled the games :)
