FYI: Extension 0.3.0 doesn't launch on QuPath 0.5.0RC1

[psobolewskiPhD]

Just an FYI that this extension isn't launching with QuPath 0.5.0RC1
My log shows:

09:28:22.180	[JavaFX Application Thread]	WARN	qupath.lib.gui.ExtensionManager	QuPath version for which the 'OMERO extension' was written is unknown!

and
