erp5_simulation_test: as `erp5_default_business_process` is required in some test cases
erp5_simplified_invoicing: as `Invoice Line` should be allowed by `Sale Invoice Transaction`
erp5_configurator_standard_accounting_template: as `default_invoice_rule` business process is needed

defined before using it as argument for isURLAncestorOf.

@vpelletier, this caused a bug, since empty came_from would crash isURLAncestorOf when urlparse is called for this url (https://lab.nexedi.com/nexedi/erp5/blob/master/product/ERP5Type/Core/Folder.py#L517). I think this is a way to solve, I do not know if isURLAncestorOf should be changed also to return something in such situation.

This ERP5 service worker provides the same functionnality than appcache (nothing more).

getOwner returns a python document.

Only support Base_jumpToRelatedObject for now.
