* 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.
