This adds the ability to access special characters in console commands by proceeding certain characters with $. See libs/util/cmd.c for the conversion table. Preceeding a character by # will shift it up or down by 128, which basically is useful for accessing the brown letters and numbers. All special characters were removed from Team_ParseSay, and variable substitution now takes the form of ${var} to prevent conflicts with special character substitution. Special character access is controlled by cmd_highchars, which defaults to off.
