This reverts commit a87db49b.

Do not remove relative url, as they are ofter use in img tag

This allow to see the content when being displayed as a web page content

details is not always the last child

On documents, we have an "Export" action for OOoDocument_viewConvertDialog.
When erp5_ods_style is installed, "Export to Spreadsheet" is added as a global
action. Both these actions were translated as "Exporter" in french, which is
confusing and a bit incorrect.
Use a proper, different translation for "Export to Spreadsheet"

This test was comparing lines returned in unspecified order, sort the lines
to be sure.

"contact us" feature of erp5_web uses erp5_crm

testTemplateTool depend on the actual order of installation of business
template, so update it now that the order has changed.

configurator scripts also had to be updated, so that
erp5_ingestion_mysql_innodb_catalog is installed before erp5_web/erp5_crm
because since erp5_crm depends on ingestion, it will install
erp5_ingestion_mysql_innodb_catalog, which has new tables and SQL methods
for indexation, so it needs to be installed with `update_catalog=True`.

As we can see here, configurator uses installBusinessTemplateListFromRepository
to install business templates one by one (in the same order that they are
added with addConfigurationItem), and pass update_catalog only for
business templates which add new tables/indexation methods and needs a
catalog update after install, but what happened is that we install
erp5_web with update_catalog=False, which will install
erp5_ingestion_mysql_innodb_catalog, also with update_catalog=False so
the activities to install business templates fail with errors like:

    ProgrammingError: (1146, "Table 'erp5_test_*.email' doesn't exist")

Since 459093f3 (ERP5Form: implement a basic checkConsistency for
ProxyField, 2021-01-26) we can detect inconsistentencies in ProxyFields
internal data structures. These are the changes after using
checkConsistency(fixit=True) for erp5_web

This relation field is used to select the web pages that will be displayed,
by using the standard ERP5 document management feature of selecting the
best applicable page with the same reference, but this list did not show
the reference of the web page

for security reasons, info on users, or existence of usernames shouldn't be leaked from the system.

manage_FTPget is an API to serve the file content to response, it is not
suitable to just get the file/page template content like we need here.
It was causing issues when running through activities, because timerserver
responses does not have the setBase method, but is also wrong because
large files are streamed to response directly.

Zope does not really offer an unified API to get the source of page
templates or files, except the PrincipiaSearchSource method which it uses
for its builtin search engine. It seems suitable to use here as well.

Also add a test for the case where web pages are in a OFS.File, only
the case of PageTemplate was covered.

Use the `ui-list-grid` class on a `ul` element.
