Title: Proper Bed Sizes for One-Up/Two-Up printers; Autolevel configuration

Defines appropriate default bed sizes for One-Up and Two-Up printers.
Also adds support for AutoLeveling using E-Stop connector to deploy the Z probe using a servo (*currently does not work properly due to limitations of printrboard hardware on pin 37*).
