Handle WSAECONNRESET, add Telnet keepalives, rework the show_conn_table.
During long-term connection testing, I found that at least one of my
connections would have some kind of disconnect - perhaps an idle timeout,
so I have added support for sending IAC NOP packets on each net loop...

Begin testing in an attempt to enumerate serial ports

Update run_menu to get it to detect a closed network connection. Also message beautification

Clean up messages and provide better help information

Implement send break function (closes #23)

Implement the ability to kill existing connections
This is a new command to force quit any current serial connection

Uncook CRLF sequences into plan CR in net_to_com
My testing had been done with the linux telnet client and it sent CR NUL
as the end-of-line character sequence. Both putty and windows telnet
are sending CR LF as end-of-line sequence. This change pretty much...

Update version number

Add telnet processing to serial-data-pump. Add ability to exit back to menu.
There is still a lot of cleanup work remaining from here. We do not need the
menu thread, we should run the menu from the net_to_com thread, however it
appears to meet the requirements. closes #16, #20
