ZipCPU f32b9622d5 Initial (random) placer capability 
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++.
