Updates to the GF180MCU tech file and device generator script for magic, which had not been validated for analog design when they were first written for the Efabless Google/GF open MPW shuttle runs (which only had support for digital designs). Fixed errors and omissions, mainly in the device generators for resistor devices. Added back the ability to turn the guard ring under resistors on or off. Also added a new feature to allow the guard ring under poly resistors to be either p-type or n-type, as both are allowable. Corrected size and sheet resistance values for the metal resistors, including all the different metal stack-up options.
