[annotator-dev] Struggling to integrate plugin with v1.2.10

Thanks Randall,

Good to know it was an accident. I've got a working implementation now by
subscribing to the 'annotationEditorSubmit' event instead and then firing
my own 'annotationCreated' event from there. It works, but I think the core
really should fire that event.

It occurred to me last night that perhaps the answer is to move the the
'save'/'cancel'/'cleanup' functions and the event bindings (lines 644-663)
into showEditor(). That way there would be no way to have a 'shown' editor
with non-functional buttons.

Having said all that, we don't use ranges, so I can't test whether my
proposal screws with whatever prompted this change.

Ta,
Greg
