use printable strings for color codes
instead of string.char(0-27), use "/" as an escape followed by
"[0-9][A-R][a-r]", all inside the string.
e.g. digiline_send("chan", "/0this /1is /2some /3colorful /4text")
"/" followed by any other character than the above will be treated as an
invalid color code and will be taken literally.
"//" will print a single slash.
Note: on receipt, all instances of "//" in a message are actually
translated to string.char(30) -- one for each pair. This makes the
scrolling code easier. Keep this in mind if you use the "getstr" and
"getindex" commands.
Also, this expands the max string length to 6 kB, to allow a full 80x25
display with one color code er character. "clear" and "allon" remain at
2kB since that's still enough.
