We need to be able to see the future without auto planned orders, else how are we going to update them?

erp5_mrp: Copy price_currency to Manufacturing Execution and Production Packing List (PSA specific?).

In PSA for ME: Problem Report is created from a ME which then build a Returned
IPL from scratch copying properties from the ME. After this Returned IPL is
root-expanded, Real Time Inventory Accounting Rule is expanded too and requires
price_currency.

As a matter of fact immediateReindexObject doesn't call reindexObject on the object

buidler: Add tmp fix/workaround on movement order

builder: Use periodicity to determinate start date

builder mixin: Take into account supply date range before create movement

builder: Hackish immediate reindex of order to work for parallel build

builder: use dedicated script to evaluate min stock

builder: autoPlan only if possible

builder: Reference of order line is reference of resource line

builder: include order delay and effective date

builder: fixup add missing part for effective date

builder: Tweak and fix supply builder

builder: Fixup supply builder

builder: immediate reindex delivery on creation

builder: use _edit on delivery to only reindex modification

builder: Supply builder work with period

builder: Supply builder improved

builder: use flow unit for min stock calculation

builder:  Supply Builder Fix future inventory for parts not activated yet

builder: Supply builder do not create movement for resources that won't be consumed in the future

SimulationTool: getNextAlertInventoryDate can look for the lowest invetory inferior to the reference quantity

With recent changes in CMFActivity, getServerAddress is now used
when setting up the site, before the ZServer is started, which means:
- getServerAddress memoized a wrong return value;
- the test didn't fail with --load.

The button "Subscribe/Unsubscribe from Timer Service" does not clearly 
explain the fact that it determines whether or not Alarms are enabled in
ERP5. It is very counter-intuitive to see Alarms on "enabled" in the 
"Configure Alarms" screen and yet not have them being run because the
Alarm Node is not subscribed to the Timer Service.

This fallback seems useless in this context, getClientAddr should be
available.

This test does not need to create an actual user as it just check
plugin extract login & password from request.
This test does not need to install the plugin in PAS, the actual check
instanciate another ERP5DumbHTTPExtractionPlugin.

- no longer needed to have same user id and logins.
- upgrader activate the plugin
