 *   Interface of generic curses IO interface
 *   (nope, it is not using curses, pure ANSI ;-)
 *   It's main piece is io_color() - it converts IRC string to terminal-ready
 *   one - so it expands ^C, ^V and ^B control chars to appropriate control
 *   sequences. Further explanation of ^C color control can be found in
 *   cursio.c - i spent one whole day by examining it and asking around whole
 *   IRC for it chaotic meaning (nope, i didn't found a definitive answer).
