* ext/tk/*: Support new features of Tcl/Tk8.6b1 and minor bug fixes.
     ( [KNOWN BUG] Ruby/Tk on Ruby 1.9 will not work on Cygwin. )
* ext/tk/*: Unify sources between Ruby 1.8 & 1.9.
            Improve default_widget_set handling.
* ext/tk/*: Multi-TkInterpreter (multi-tk.rb) works on Ruby 1.8 & 1.9.
     ( [KNOWN BUG] On Ruby 1.8, join to a long term Thread on Tk
       callbacks may freeze. On Ruby 1.9, cannot create a second 
       master interpreter (creating slaves are OK); supported master
       interpreter is the default master interpreter only. )
* ext/tk/lib/tkextlib/*: Update supported versions of Tk extensions.
         Tcllib 1.8/Tklib 0.4.1  ==>  Tcllib 1.11.1/Tklib 0.5

* ext/tk/lib/tk.rb: avoid trouble when finalize TclTkIp.

* ext/tk/lib/tk.rb, ext/tk/lib/tk/*: help to fix troubles when 
  use Ttk widgets on old Tk scripts.

* ext/tk/sample/*: update and add demo stcipts. some of them are 
  introduction about new features of Tcl/Tk8.5.

  Now, support longnam-keys (e.g. '%CTT' on tkdnd-2.0; however, still
  not support tkdnd-2.0 on tkextlib), and symbols of parameters (e.g. 
  :widget=>'%W', :keycode=>'%k', '%x'=>:x, '%X'=>:root_x, and so on; 
  those are attributes of event object). It means that Ruby/Tk accepts
  not only "widget.bind(ev, '%W', '%k', ...){|w, k, ...| ... }", but 
  also "widget.bind(ev, :widget, :keycode, ...){|w, k, ...| ... }". 
  It is potentially incompatible, when user passes symbols to the
  arguments of the callback block (the block receives the symbols as
  strings). I think that is very rare case (probably, used by Ruby/Tk
  experts only). When causes such trouble, please give strings instead
  of such symbol parameters (e.g. call Symbol#to_s method).

* ext/tk/lib/tk/event.rb, ext/tk/lib/tk/validation.rb, 
  ext/tk/lib/tkextlib/blt/treeview.rb, 
  ext/tk/lib/tkextlib/winico/winico.rb: ditto.

* ext/tk/tkutil/tkutil.c: strings are available on subst_tables on 
  TkUtil::CallbackSubst class (it is useful on Ruby 1.9). 

* ext/tk/lib/tk/spinbox.rb, ext/tk/lib/tkextlib/iwidgets/hierarchy.rb,

  unnecessary by reason of the changes of ext/tk/tkutil/tkutil.c.
