This break existing stored data, though we assume this is not an
issue since this is not used yet except for a prototype

Use a development version based on renderJS 0.7.2.
Stop using development RSVP.

If it has to be fixed, do it on the server.

Use _download_local instead of _importBT because this method was removed

Experimental BT for now. See description

was too fast in previous attempt to fix the issue

regression introduced with commit cacea29b

Inventory API has minimal catalog table usage (join on uid  only), which
makes on-deletion catalog changes insufficient to make movements
disappear transactionally from Inventory API results.
As it may be expected that a set of movements deleted during a single
transaction are atomically removed from Inventory API results, also
change stock table.

If an object has no uid yet and has no acquisition context to the portal,
getUid() fails.

Default is derived from id(aq_base(ob)) which is even more efficient.

The method on XMLObject was also redundant because it inherited the same one
from Base.

Because on DVCS with branches, history is not always linear, we must stop
using increasing integer for revisions because they cause too many conflicts
and a higher revision number does not necessarily means the a BT newer.
They're now a cryptographic hash of all the contents of the Business Template,
and they're computed automatically:
- by genbt5list
- at download
- at building (by default)
- at export

Add test to simulate the issue with the method TemplateTool.installBusinessTemplateListFromRepository

Using the method try to install Business Templates that are already
installed, the Business Templates is uploaded on ERP5 but not used. It
creates a lot of garbage because in the end you have many bt5s not
installed.

Considering erp5_configurator_ung depending on erp5_configurator which in turn
depends on erp5_workflow, if erp5_workflow and erp5_configurator_ung are
specifically added to the list of bt5 installed with depends, then erp5_workflow
ended up being installed *after* erp5_configurator.
