Fix bug #951 and renamed Application Proxy states

Fix bug #951, the App Proxy now enters a 'completed' state when its
running application instance has finished its execution. Once in that
state, it cannot run a new instance of the same application again.

To be consistent with our approach of manipulating resource states
rather than requesting actions from resources, I also renamed the
states of the App Proxy from 'run', 'stop' etc... to 'running',
'stopped', etc.. This also required a change in the EC backward support
for 5.4 OEDL.
