Added an EvolutionActivityClient object to libeshell, to handle
updating of progress information from the component's side. This object allows to automatically set a lower limit to the delay between CORBA calls towards the shell, so that the component isn't slowed down too much by doing too frequent updates. Also changed the test component to use this instead of doing CORBA calls directly. svn path=/trunk/; revision=10449
