Terminate loop when canceling waiting for wifi.
Implement ABOR, HELP, and STAT.
- STAT (no argument) during a transfer gives the current file's offset.
- STAT (no argument) outside of transfer will return server uptime.
- STAT (with argument) is the same as LIST but with the data traveling over the command socket.
Allow ABOR, STAT, and QUIT to occur during transfer.
Support telnet interrupt (discard data up to Data Mark past TCP urgent mark).
Support arguments for LIST and STAT.
Escape \r in response as per telnet standard. Some clients don't like this but they are out of spec.
Unescape \r\0 in request as per telnet standard. Some clients don't properly escape this but they are out of spec.
Support commands broken across multiple recv().
Escape quotes on PWD response.
Added much more documentation.
It's better to give an output name instead of using the name of the current directory, so 'ftbrony' is used as default. I also fixed the icon not being used in SMDH creation (project name is ftbrony-master when downloaded from GitHub, not ftbrony).
