Either EcoGrid registry or Master should check the heartbeats from slaves. But
the services at EcoGrid are to respond the outside invocation, not to execute
itself periodically to check the heartbeats. In theory, Masters can check
heartbeats of slaves. But we'd better remove unavailable slaves when users use
‘Distributed Computing Options’ menu item from Master side to check available
slaves. Otherwise, the registered unavailable slaves are confusing and useless
to Masters. 

So I modified the code for ‘Distributed Computing Options’ menu item at version
23397. Now the availability of all registered slaves will by checked, and the
slaves will be de-registered and not show up if they are not available.
