* configure.in qt/Makefile.am: add qt/examples

Browse source 
* qt/examples: Add QtDBus example programs:
	  - hello: Hello, World
	  - ping: Simple method-calling program
	  - pong: Simple object-exporting program (not using adaptors)
	  - complexping: Interactive method-calling program
		(also gets and sets properties).
	  - complexpong: Sample program exporting methods, signals and
		properties, using adaptors.
	  - dbus: Simple implementation of a generic method-calling
		program, similar to 'dbus-send', but with semantics
		similar to 'dcop'.
	  - chat: Simplistic chat program, implemented using signals
		and the system bus. Looks like IRC.
