Removed some vestigal code from 'goodfet.cc reflex'.

Introduced 'goodfet.cc infotest' which repeatedly request the chip info to distinguish between a bad connection and a flaky one.
GoodFETCC.py now retries an initial connection if the info return 0xFFFF or 0x0000, fixing some issues with capacitors on !RST lines.
