[tcltk-perl] Tcl::Tk recent changes

[Konovalov, V. <vko...@sp...>]

I did some commits, and few more commits are to be done.

Among those that will be commited today/tomorrow:

  - removing "awidgets" method, described in POD and removing it from POD
too. I hope no-one stuck with it to the moment.
  - pkg_require will recognize packages on interpreter basis.
  - widget method of interpreter object should *optionally* get second
parameter, and, if given, bless widget to that package
Tcl::Tk::Widget::WIDGET-TYPE so to allow be fully identical to call either
way:
  $widget=$mw->Text;
or
  $interp->Eval('text .t'); $widget = $interp->widget(".t","Text");
(otherwise widget .t will live in "common" space and probably could mess
methods)

 After "pkg_require" change "tcltkdb" started working more or less robustly.
I am thinking about proposing people actually use it, as it looks quite
normal, yet allows debugging Tcl::Tk GUI with Tcl::Tk GUI, and here 2
interpreters come into play

Looking for timely objections or silent agreement :)

More documenting also prepared, but... there are many but-s in mydocumenting
.

Best regards,
Vadim.
