* ext/tk/lib/tk.rb: forgot to update RELEASE_DATE

* ext/tk/lib/tk.rb, ext/tk/lib/tk/text.rb,
  ext/tk/lib/tkextlib/iwidgets/scrolledtext.rb: remove adhoc check 
  of Ruby's features (use existence of some classes instead of 
  comparing with RUBY_VERSION)

* ext/tk/lib/tk/root.rb, ext/tk/lib/tk/autoload.rb: make TkRoot 
  (Tk::Root) unswitchable

* ext/tk/lib/multi-tk.rb: partial bug fix (still not work!!)
