Added escape characters, the <i> tag to ignore tags enclosed within it, and

generally cleaned the parser up.  If a line begins with |, it will be
stripped off by the tokenizer and no tags or escape characters will be
processed.  Commands stuffed into the console from the server are prepended
with | to ensure backward compatibility.  This can also be used anywhere
backward compatibility is needed, such as where info strings are stuffed
into the console, or as an alternative to using escape characters in the
entire string.
