* 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.
