Subject: * ext/tk/lib/tk.rb, ext/tk/lib/*: make default widget set  
 switchable between Tk (standard Tcl/Tk widget set) and   Ttk (Tile). Initial
 default widget set is Tk. Now, toplevel   widget classes are removed and
 defined as aliases.   For example, "TkButton" is an alias of the "Tk::Button"
 class.   Those aliases are replaced when switching default widget set.  
 "Tk.default_widget_set=" is the method for switching default   widget set.
 "Tk.default_widget_set = :Ttk" defines Ttk (Tile)   widget set as default. It
 means that "TkButton" denotes   "Tk::Tile::Button" class. And then,
 "TkButton.new" creates   a Tk::Tile::Button widget. Of course, you can back
 to use   standard Tk widgets as the default widget set by calling  
 "Tk.default_widget_set = :Tk", whenever you want. Based on   thie feature,
 you can use Ttk widget styling engine on your   old Ruby/Tk application
 without modifying its source, if you   don'tuse widget options unsupported on
 Ttk widgets (At first,   call "Tk.default_widget_set = :Ttk", and next load
 and run   your application).   This is one step for supporting Tcl/Tk8.5
 features.
