Subject: implemented ^C command

 * acts like exit(3) -- ie. the program is terminated
   immediately but the quit hook (aka SciTECO's atexit()
   handlers) will still run.
 * for "compatibility" with classic TECOs.
   Can also be used as a shorter variant of "-EX$$"
   but working from every macro level.
 * disallowed in interactive mode to avoid typing it
   accidentally.
