Made the external D-Bus interfaces a compile time option

Running qmake -config disable-external-dbus-interfaces will now compile out the
support for all the external interfaces (ApplicationManager, WindowManager,
ApplicationInstaller and NotificationManager). This also cleans up the
implementation of these singletons, since we are now using a custom "2 step"
DBus adaptor to get around the QtDBus limitation that requires the original
object to derive from QDBusContext (although this violates every layering
rule).
In any case, this will not affect the private P2P Bus between the AM and the
apps.
