Bug: Remand function is just plain bad, will give bad strings.
Danger: Medium
Found by: Anonymous
Fixed by: Terell
-----
(functions.c)
Replace the original remand function with:

/*
 * This function will remove all & and ^ color codes out of a string
 * Rewritten by Terell so that it won't cause static variable problems.
 */
char *remand( const char *arg )
{
   static char ret[MAX_STRING_LENGTH];
   char *retptr;
   retptr = ret;

   if( arg == NULL )
      return NULL;

   for( ; *arg != '\0'; arg++ )
   {
      if( *arg == '&' && *( arg + 1 ) != '\0' )
         arg++;
      else if( *arg == '^' && *( arg + 1 ) != '\0' )
         arg++;
      else
      {
         *retptr = *arg;
         retptr++;
      }
   }
   *retptr = '\0';
   return ret;
}



Note that one problem that arises from the old function is you cannot introduce yourself because do_introduce calls remand to strip the argument of color codes. Guess what? The old remand gave a blank string.... This should fix that.
