* use <copyPaste.canCopyProperty> event to copy category value when copying group
* add camunda-bpmn-moddle for integration tests
BREAKING CHANGES
* CopyPaste: remove <property.clone>, add <moddleCopy.canCopyProperties>, <moddleCopy.canCopyProperty>, <moddleCopy.canSetCopiedProperty>
* BpmnRules: removed <elements.paste> rule in favor of <elements.create> rule
* BpmnRules: removed <element.paste> rule
* ElementFactory: use <attrs.di> property instead of <attrs.colors> for fill and stroke when creating element through ElementFactory#createBpmnElement
This simplifies the ways we work with replacements.
Instead of monkey-patching the original replace functionality we
* create the business object / target object
* pass it to replace
A simple way that works well with our existing infrastructure.
Other changes:
* fixes redo / undo issues.
* splits context-pad + replace
