This commit also includes changes to jsonparse to allow it to 1) recognize ports with no connection, and set their net pointers to NULL 2) recognize designs with a ports node rather than a ports_direction The rule checker has also been modified to accommodate possible NULL netlists The ice40 chip now also has iterator operations ++bi and bi++.
