test.erp5.testUpgrader.py: the bt5list update in afterSetup() includes the case of several business templates locations

It includes the following bt5 :
  erp5_property_sheets: replace the journal category in Movement by the ledger category
  erp5_configurator_standard_trade_template: replaces the base category journal by ledger in simulation rules
  erp5_project: replaces journal base category by ledger
  erp5_research_item: replaces the journal base category by ledger
  erp5_mysql_innodb_catalog: replaces queries containing journal by ledger

runUnitTest: recreate_catalog doc saying 'Default is not to recreate, unless using --data_fs_path' was incorrect. Check lines 723, 758 and 765. So default is not to recreate.

erp5_data_notebook : Check for matplotlib.pyplot module object in Base_displayImage

The external method Base_displayImage displays images of two kind: plot and OFS image
saved in erp5. We had earlier checks for erp5 images but no check to for matplotlib
plot images.

Please review: @Tyagov

Instead, define default values if not set (same as previously hardcoded
ones) and get the value(s) define on the Tester instead as we may want
to check only variation_category_list and not variation_property_dict
for example...

simulation: MultiPropertyEquivalenceTester was missing from Variation Divergence Tester Portal Type.

This makes more sense as all Tester inherits from EquivalenceTesterMixin,
even project-specific EquivalenceTester classes.

Also, define getTestedProperty{List,Title}() for compatibility sake as
they are still widely used.

Followup of: "simulation: improve equivalence testers explanations messages".

With latest simulation, the explanation given to user when solving a
divergence was not good enough :
- Property ids were displayed without possibility to display
  business word (like displaying 'stop_date' instead of
  'Delivery Date'
- Some message was displayed in the solve divergence dialog whatever
  was the equivalence tester behind. Therefore, customizations of
  messages made a equivalence tester level were not displayed to user

Therefore, following was done:
- in solve divergence dialog, include the message generated by the
  equivalence tester
- use tested_property_title to allow using business words to describe
  properties having divergence
- most equivalence testers are written in a way to evaluate divergence
  on a single property. To have better UI configuration of such equivalence
  testers, change tested_property and tested_property_title properties
  type from "lines" to "string". This required to add some backward
  compatible code.
- use Variation Divergence Tester to show a case of an equivalence
  tester using different properties. For this, add a property sheet
  dedicated to multi properties equivalence testers
- update propertysheets to allow translating tested_property_title

When RSPL/RPPL Invoice Lines are on the same SIT TML as its
corresponding SO/PO IL movements, the sum may be 0 and there is nothing
wrong about it. This was implemented in Legacy Simulation.

With Legacy Simulation, when Adopting Prevision, the Builder was called
again and the value was set either at Delivery, Line or Cell level
according to the Movement Group definition. Implement the same kind of
behavior for New Simulation.

count_method was removed from Base_viewFieldLibrary/my_view_mode_module_listbox
used by Resource Module ListBox (76282344) for performance issues when
countFolder is called with a Module containing > ~50k documents but this
should not be relevant for Resource Modules.

change unmaximize button to Alt-m, set focus to ace editor after maximize

escape button for unmaximize is useless because the close of search dialog
 (ctrl-f) conflict

The external method Base_displayImage displays images of two kind: plot and OFS image
saved in erp5. We had earlier checks for erp5 images but no check to for matplotlib
plot images.

erp5_web: WebSite_login: do not redirect to a came_from that is not child of the topmost url document in the given instance.

erp5_base.Base_getURLTopmostDocumentValue.xml: add a method to get the topmost traversed url in an ERP5 instance. In base it returns the portal.

Class FolderMixIn: add isURLAncestorOf method. Returns True if the given_url is child of the url of the given_url is child of the url of the document that the method is called on, False otherwise

This is too inconvenient when resizing browser size, it requires in
some cases to do taller or shorter many times only because we resized
the browser.

Also, former way was not working nicely when editor like code mirror
was used
