This commit updates the default direct editing behavior.
It activates on non-touch environments only and only on embedded
labels, too.
This provides a way smoother modeling experience.
This commit puts all import related stuff into the import module.
The core module remains as an entry point to require the basic modules
needed by bpmn-js. At the time this is { import, draw }.
This commit improves the label handling by
* showing the label only if it exists
* updating the status accordingly
* positioning the label correctly on import
Related to #113
