* qt/dbus: Add directory. I had forgotten to add this

	yesterday after the move...

	* qt/examples/Makefile.am:
	* qt/examples/dbus.cpp: Moved to qt/tools/dbus.cpp.

	* qt/tools/Makefile.am:
	* qt/tools/dbus.cpp: Moved from qt/examples/dbus.cpp.
	Added feature to get and set properties.
	Added validation of service, object path and interface names.

	* qt/tools/dbusidl2cpp.cpp: Two new features:
	1) Allow specifying both the header and the source file names,
	by separating them with a colon.
	2) Don't write an interface output if the -p switch wasn't
	given, but the -a was.

	* qt/src/*: Fix usage of Iterators and ConstIterators.
	Fix shadowing of variables by other variables (-Wshadow).
	Fix keyword-cleanliness in headers.
	Fix ASCII-cast (QLatin1String, QLatin1Char).
	Fix validation of member names.
	Add extra checking of introspection data during XML parsing.
	Various bug fixes.
