NiceSpot trunk

-Now supports 7-bits mode (7-E-1, 7-O-1, 7-E-2 & 7-O-2.

-A few new command on console side to control the sniffer port to enable/disable.
-The time stamp feature is now enabled.
-The detection of the 9th bit is now enabled.

-Now emulating a total of FOUR serial port. The last three are used to send back data of three pair of communication between master and device we're sniffing.

-Reintegration of original comments from Harmony that was removed by accident.

-Modified in such way that data sniffed is now received totally on a separated COM port.
-So from now on, NICESPOT will be seen with as a pair or TWO COM port:
1o) One for the console to send and receive command.
2o) One for the actual sniffed data.

-Added some pictures of the evolution of the project, from a physical perspective.

-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.
