------------------

natively, alleviating the need to have module_auto_update installed in the database,
and is more robust (it does a regular -u after identifying modules to update)
- upgrade: deprecated in favor of click-odoo-update
- initdb: save installed checksums so click-odoo-update can readily use them
- initdb: add --addons-path option
- copydb: fix error when source filestore did not exist
