* regtool.cc: Throughout, convert all registry calls to wide char

calls and use string conversion according to current locale.
	(longopts): Change "dword-le" to "dword-be", as was originally
	intended.
	(usage): Change usage accordingly.
	(print_version): Simplify copyright dates in output.
	(cmd_list): Handle REG_LINK like REG_SZ.
	(cmd_get): Ditto.
	(main): Call setlocale.
	* utils.sgml (regtool): Fix options and add missing descriptions for
	new features.
