DocView and ActiveGrid IDE updates from Morgan Hua:

New Features: In Tab-View mode, Ctrl-number will take the user to
    the numbered tab view.  Modified files now show an '*' astrisk in
    the view title.  Debugger framework can now support PHP debugging.
    Not important for python development, but at least that means the
    debugger framework is more generalized.
