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++.
