Once #1475 is complete, populate part data for all parts that fabric documentation exists for. #1475 should be done first to avoid duplicating all of the fabric data repeatedly.

The testing/mdd_make.tcl program generates a .mdd file which then takes 100 lines of python to parse. Bad use of effort.

Have .tcl output a .json file which can be trivially read. Updates to resulting data structures may be needed (or converted to dictionaries).
