Change EndpointView and StaticEndpointView to create our own endpoint element which can host multiple jsPlumb connections (and use jsPlumb endpoints as 'handles' to move or clear connections)
Allow EndpointView derivates to optionally be sources, targets, or both
Set the offset property of StaticEndpointView instances using .prototype.defaults to allow it to be overriden
StaticEndpointView -> ParametricEndpointView
plumb(Source|Target)Opts -> plumb\1Options
Uncomment failing TableFormView view tests, use skip instead
Fix bad module title for go.testHelpers
Fix bad test description for EndpointView test
Add a patched jsplumb vendor lib with the global leaks fixed, use the patched lib for tests
Skip failing TableFormView test
Add jsPlumb leak fix diff
