[Erp5-dev] Generic management of local roles

[Jean-Paul Smets]

Hi,

I have added to ERP5Type a subsystem to manage local role assignments in a
generic way. Until now, we have been using custom init scripts to set local
roles at document creation.

Based on the current experience, we have added a Roles tab to ERP5Type to
define:
- a role definition name
- the local role which is defined by this role definition
- the condition of application (TALES)
- static categories which should be used to determine group membership
- base categories which should be used to determine group membership
- the user or object on which such base categories should be used to
calculate category membership

All this information is evaluated at instance construction time then passed
to the "ERP5Type_initLocalRoleMapping" script (or extension).

JPS.
