This is required with ERP5JS, where every save call render with new data.

When no schema for the edge, don't try to show edge edition dialog. Until now
this was crashing

 - make the gadget full page, this is better when using in an iframe
 - "highlight" the currently hover edge, which makes the graph more readable
 when there are overlapping edges.
 - user helvetica font every where

This introduces a new gadget_graph_editor.html gadget, for use in iframe and
keep the existing dream_graph_editor/jsplumb/index.html for use in "public"
scope, ie. without iframe.

as explained in comment, this API is asynchronous but the promise to await is
not exposed

At the beginning of tests, there is Tests completed in {a few milliseconds}, so
this was reporting success before the test even run.

 - We don't care about a stable random layout, we want to include the
manual layout in business templates
 - Re-add edge edition dialog that was removed
 - Drop a wrong CSS that was removed long time ago but re-added by mistake
 - Don't do CSS in the javascript, the graph model allows to have CSS in
the model

Since 9f6178cb (product: Add Web Illustration to the seperately exported
property dict, 2021-06-23) the export format is different.

CodingStyle detects this and report it as a failure, so re-exporting is
required for the test.

For consistency with default ERP5JS and because it's convinient to have the
jump here, to access the document tab that is now a jump action.

- migrate from appcache to precache script

Then the user can select the prefered language in the ERP5JS UI

erp5_configurator_standard

The previous implementation will generate URL like:
erp5/test_page_module/core/TestRunner.html?
Which missed the test created in portal_tests, the correct one should be:
erp5/test_page_module/portal_tests/user-Howto.Create.Persons/core/TestRunner.html?
