- Update API and interfaces
- Make it possible to:
  - do non-linear calculation (via global type-based script)
    for every considered base_amount
    (i.e. not only for base_application of input movements).
    To avoid performance issue, the type-based script is changed to return
    functions instead of calculating results directly.
  - get accumulated values from movements while generating amounts for a
    delivery (i.e. for Amount Generator Lines targetting deliveries).
- Produce amounts even if there is no resource, for reporting.
- Drop probably useless create_line property: checking if there is a resource
  should be enough.
- Prepare refactoring of MRP/Trade/Payroll by introducing AmountGeneratorLine
  class and property sheet.
- Stop doing anything if there is no base_application on an AGL to avoid
  conflicts while figuring out if a movement was created manually or not.
- Update some forms.
- Update testTradeModelLine
