Kepler

The documentation is almost done. Several small issued to be discussed with Ilkay.

update section 7 to explain more about SRB actors, which are still working when the host and resource server are running.
I think the bug can be closed.

With the Jargon.jar in Kepler, it can communicate with different SRB version. Since SRB has not been updated for two years and will probably also not be updated, the current SRB actors are able to work with all different SRB version.

Original Bugzilla ID was 4076
