Allow edition in the new UI

This make everything slow as hell and prevent to quickly save.

This is the loyalty programme for commerce.

Idea is to use modelled trade model lines, at least three lines are needed:

  + One trade model line to define how to collect loyalty point

  + One trade model line to define how to use loyalty point
  + One trade model line for discount
  + .....

New loyalty transaction is added to record loyalty point.

testERP5Simulation: Improve test_02_splitAndDeferAfterAcceptDecision. After SplitAndDefer, expand the root applied rule and make sure that two SPLs are not diverged.

Tool/ContributionOpener: Moved its content (DirectoryFileHandler class) to ContributionTool as this is not a Tool.

As this is only used in ContributionTool, it does not seem necessary to create a separate
module for that.

Also:
  * Fix undefined variable `splitport`.
  * Use cStringIO instead of StringIO (as the rest of ContributionTool code does).

erp5_demo_maxma_rule: Add depend on erp5_accounting as it uses AccountingTransactionRootSimulationRule Document migrated from FS (a0c2b666).

This fixes CodingStyleTest tests.

erp5_simulation: Move Solver-related Python Scripts not used in erp5_base to erp5_simulation (a7d6edba).

This fixes test_SkinCodingStyle for erp5_base: 'Wrong prefix Solver for python script
Solver_getDefaultConfiguration...' as a result of ISolver migration from filesystem).
