New extrusion class: ExtrusionMultiPath

This is similar to an ExtrusionLoop, but it is open.
It may contain multiple chained paths with differing parameters.
This allows one to have a hierarchy of paths, where the ExtrusionEntityCollection
will be chained by the G-code generator, but ExtrusionMultiPath will not.
