[tcltk-perl] internal changes to Tcl::Tk - more needed

[Jeff H. <je...@ac...>]

I jiggered some stuff around in Tcl::Tk that touches everything
essentially - how the basic object stuff is managed between
widgets and their data.  I fixed it up to have "instance data",
but it was a rough botch.  There are several limitations that I
did not work around.

I plan to rework all this tomorrow by changing Tcl::Tk to have
each Tcl::Tk object start with the instance control, like the
interp and the %W hash.  This will trickle down through all the
other bits (hopefully).  Each widget will be an object that can
have instance data, overloading the stringify to return the path.

I think (hope) this will address the limitations as well as
making the code simply cleaner.  If anyone has reservations or
great ideas, give them now ...
