	First import of Ttk themed Tk widgets as branched from tile 0.7.8

	* generic/tkInt.h, generic/tkWindow.c: add Ttk_Init call, copy
	tk classic widgets to ::tk namespace.
	* library/tk.tcl: add source of ttk/ttk.tcl, define $::ttk::library.
	* unix/Makefile.in, win/Makefile.in: add Ttk build bits
	* win/configure, win/configure.in: check for uxtheme.h (XP theme).
