This fixes a regression in recent commit 6e758ade

The following line:

  simulation_movement_list = delivery_dict.get(movement) or \
    movement.getDeliveryRelatedValueList()

didn't work because the loop that fills delivery_dict does not necessarily
find all related simulation movements for every key.

New code is a little complicated because it tries to not call
getDeliveryRelatedValueList() when 'movement' is not related to trade model.

This tests try to install a business template that modifies the catalog,
if it fails, it is required to launch recatalog to update MYSQL
 information, otherwise the further tests will fail due the lack of the
email table present.

Now as default, the tests prefer local bt5 folder if it is a repository.

With the usage of git branches, this changes helps the developer test
his own local changes before merge with master (branch used to generate
snapshots)

cf commit edb4be56

This fixes ERP5SyncML and ERP5DocumentSyncML tests failures as erp5diff
doesn't support merging of XML with nodes with the same ID.

This fixes 43c8d0b5.

This reapplies commit ddcb5001,
now that we have no more unexpected success.

This test was fixed by commit df7ee3a3
("specialise should be copied into Delivery instead of Movement in PL builder").

Use only one global RenderJs variable to access different modules instead of many global variable here and there.

Use scope and closures to make all gadget module alike.

Add a test about checking quantity unit behavior on movement. Quantity unit set to movement must not be changed by changing default quantity unit on resource. This test will fail as expected.

add new assert to support range of values expected. The position is calculated on planning box and is returning small difference on value in each testnode result. With this, the test was changed to support this range.

TIDStorage monkey-patches ZEO so it imported it before 'custom_zodb' is loaded.
This commit fix 'custom_zodb' to reset ZEO triggers.

This revert a wrong change in commit 8995b645

Move active context creation, active callable creation, packet length test
out of loop.

That change makes no sense latency-wise, iteration will anyway happen
inside "list()". Also, it potentially degrades memory usage.

use key press instead of click on button save to avoid permission denied failure with selenium and firefox
