NiceSpot trunk

-Sniffer serial port have been tested successfully.
-We're able to receive data, put them in a buffer and send back buffer to pc.
-Data sent to PC is sent via cctalk packet. For the moment it has the "ACK" on 4th byte but soon it will be a 0x0A to signify INTERRUPT which will mean a packet out of current sequence of communication. This way, host will be able to talk to the NICESPOT without the incoming sniffing data to interfere.

-Adjust interrupt levels of serial ports.
-Notes for the PCB to add something to connect a logic probe! :-)

-Documentation for cctalk was added.

-Initial cctalk implementation.
-It can received and reply to given order.
-Source is made in such way that cctalk could be re-use for another application and keep having the cctalk related stuff re-usable.

-First compilation!

-First import!
