fixes#1362
Ignoring qty_available for phantom products prevents double counting the
qty_available of components.
Creating planned orders for phantom products is simpler than recursively
exploding phantom BOMs. This also makes it easier to analyze the planning data
generated by the MRP calculation.
For each MRP Parameter or for each Product in a MRP Area, we will be able to add a MRP Planner. Once this planner is set, he can filter himself in the MRP Parameters view, MRP Inventory view or MRP Planned Orders view.
* keept description of planned orders verbose.
* make it translatable in most cases.
* while grouping demand include the product in the description.
* add `origin` field not mrp moves and planned orders. Fill it
with top level demand origin.
* Add menu entry for planned orders
* Add button to navigate from planned orders to linked manufacturing orders
* Add action to convert planned orders to fixed
* When changing the due date in a planned order the release date is recomputed
* Planned Order release and due date become required.
* Add button to Product MRP Area to update MOQ from Supplier Info.
* Link Manufacturing Orders with Planned Orders.
* Allow Mrp Inventory Procure Wizard to be used from other models.
* Make MRP Inventory creation more extensible.
* Main Supplier computation (v13 requires explicit False definitions).
* You can know integrate with different forecasting mechanisms.
As a consequence integration with stock_demand_estimate is moved
to a new module (mrp_multi_level_estimate).
* As agreed by the authors, the module is re-licensed to LGPL-3.
* fix api.depends fields fro main supplier.
* fix ordering and missing demo file in manifest.
* Update README.
* fix action_view* methods.
* readd hook to exclude in mrp initialization
* fix computation of qty available (it was considering several times sub-locations).
* Remove contraint for outoing and incoming moves to be moved in/outside the company, they can be internal transfers.
* mrp.moves visible with technical settings.
* Show product and allow to search by it in mrp.inventory.
