Update README.md
Fix the PIC24 MIB lock-up bug (interrupts during rpc_queue were the issue).  Also move logging code to shared (technically it's more of a mainboard thing, but it would work anywhere with flash and cen be utilized here to add logging in shared code too.  Finally, add a bunch more logging of different things different places.
Re-add commented out line (for multiple registered comm modules)
