Need to centralize "propertyTester" and earlyStart #237
Description
Historically the propertyTester (used by plugin.xml to filter actions) was duplicated in each engines UI (ie. moccml engine, java engine, ...)
In order to properly work, the enclosing project must be started, so these projects were started using the early startup extension.
in 4248e8f this was partially centralized in org.eclipse.gemoc.executionframework.engine.ui
as the propertyTesters in the different engines are actually completely the same, we need to finish this centralization for all engines.
- need to enable earlyStartup on
org.eclipse.gemoc.executionframework.engine.ui - provide a property tester in
org.eclipse.gemoc.executionframework.engine.ui - changes all plugin.xml to use this property tester
note: this previous partial refactoring , raises many errors in the test logs, such as
org.eclipse.core.runtime.CoreException: Plug-in org.eclipse.gemoc.execution.concurrent.ccsljavaengine.ui was unable to load class org.eclipse.gemoc.execution.concurrent.ccsljavaengine.ui.ModelingWorkbenchEarlyStartup.
at org.eclipse.core.internal.registry.osgi.RegistryStrategyOSGI.throwException(RegistryStrategyOSGI.java:212)
fixing this should also fix these errors
