Repair original testCheckPDFThumbnail by updating the link name from
Preview to Thumbnail, as a follow up to fe83821b

we are now using setFile selenium command to upload file from an URL.

this test is running with FCK Editor as preferred text editor

This was for very old firefox and have been ineffective for years.

This reverts part of 2fcab04e , which for some reason was patching
doType that was not used because defined in user-extensions.

When test fails because of assertion failure inside an iframe, it's also
helpful to dump iframe content as well.

HAL JSON uses JSON, which uses UTF-8, but properties of ERP5 documents
does not enforce any specific encoding, so if we happen to have
documents with string properties that are not UTF-8 compatible, they
could not be queried with HAL JSON (json.dumps was raising UnicodeError)

This pre-process field default properties and document title to make
sure they can be serialized as json. This assumes that configuration
(form definition, actions, ...) will be valid UTF-8, but just does extra
effort to make sure "broken" data can be displayed without error.

ZODB Components: 'Migrate Components from Filesystem to ZODB' view: Fix ListBox to display selected ones first.

In this context, 'selected' means classes found by introspecting Portal Type
Class MRO. This was not sorted properly only for filesystem Products.

ZODB Components: Do not automatically validate when importing from FS as imports have to be adjusted manually.

Besides not being actually needed, checkPythonSourceCode() was called on all
temp_objects created for migrate_component_from_filesystem Business Template Action.

Thus adjust accordingly. Do not mix http and https.

Editing instance parameters will automatically trigger instance update at node and there's no need to stop / start instance.

evaluated before timeout and thus causing unexpected AttributeErrors
later.

password pair generated (in some cases this might happen after frontend
generation leading to 403 HTTP error codes in bootstrap code.)

Cleanup conditional code.

code will fail with :
"local variable 'user' referenced before assignment".
As callee is handling the possibility of delayed frontend and / or
instance creation this is perfectly fine.

[erp5_hal_json_style/erp5_web_renderjs_ui] Render the form directly after a successfull call to Base_edit

This decreases the query number from 2 (POST to Base_edit -> redirect + GET to render the form) to 1 (POST to Base_edit -> render the form) and so improve the speed of ERP5JS.

To achieve this, apply so fixed in ERP5JS:
* rerender the panel/header after Base_edit (router is not called in such case, so, it must be manually called)
* fetch the page title from the form calculation (as the document context is not recalculated, only the form)
* force deleting the current field values, used by the relation field listbox search

This commit also force the full page refresh when diplaying a new document, in order to prevent keeping field values from the previous one (so bugs used to occur when using the previous/next document pagination).

Thanks to Tristan Cavelier for his work on this topic.

With a minor update of ghostscript, we again had weird changes:

AssertionError: 'ERP5 is a free software.\n\x0c' != 'ERP5 is a free software.\n\n \n\x0c'

URL convertion has to be done by javascript so that the code become useable for officejs.

This reverts commit 9f8dd82c.
