remove portal_web_services from erp5_base
add required dependencies on bt5

Use the same detection scheme as Formulator.
Extends a bit further rampant code duplication.

Revert "Use default Person's site & group as set by respective Career settings (not any more Person's Assignments)."

This reverts commit 9e376960.
Afterall, it seems more logical to use assignments because security depends on
assignements, so a user with inconsistent careers definition could create a
document that he cannot view/modify

Items are used on tasks for generating reports

This is useful for some reporting

Instead of hiding those lines and printing an incorrect document it's safer to
let the unauthorized error happen.

Simulation relationship fails in (at least) two cases:
- cancelling an invoice which was entirely created by simulation would
  create an empty invoice
- cancelling an invoice with simulated accounting lines generated from
  temp-object-based simulation would copy those lines, while they should
  not be copied
Also, implement recursive copy of Invoice Lines, as (per portal type
definition) they can be arbitrarily nested.
Also, prepare a place-holder for Invoice Cell copy. As I do not have a
document with cells at hand, and do not know all relevant properties, I
decided to keep this code disabled and raise.

Acquisition Portal Types is same as for resource.

Example of categories:

journal
  accounting
    consolidation
    national
  project
    deliverable
    r_and_d
  qa
    invalid
    fixed
    wontfix
  trade
    prediction
    reality

Contain objects and scripts needed to perform scalability tests.

Without sort the item list is hard to select the variations and most of the time are many

- columns are now searchable
- title display line title if any; for consistency with all other reports
- title is no longer sortable properly. This is a little regression.
- use queries instead of raw where expression

Allow to close a draft position.

trade model and invoice transaction line should be in same invoice
