Display in the mode-line that Javascript is enabled, to warn user.

Browse source 
This is accomplished by having a global variable have access to the mode_line
update function, and having that global invoked upon change.  I made some
attempt to do this by using:

    global_update_mode_line_for_javascript =
       function () {  watch_pref("javascript.enabled", obj.do_update);};

However, I couldn't figure out where to call that so that it always worked at
the right moment.  This solution is probably simpler in the end.
