instead of building HTML in python, it's cleaner and prevent problems when attachments names are HTML entities.

erp5_base portal_actions/jump_related_object: Generic jump action should be lower priority than other dedicated jump actions.

because storing as document depends on erp5_ingestion & erp5_dms

On both the "create new support request" and "post new message on an
existing support request", enable the "Maximize" button so that users

If we have a dialog with an editor field in bottom group, then dialog
action buttons does not fit on the screen.
Until rjs_gadget_erp5_nojqm.css allows using editor in bottom groups of
dialog, let's put them in center group, because editor in center group
have "normal" size and the action button fits.

This reverts commit 11b815bc.

This approach was not enough to solve on all dialogs the problem that
button is not always on the screen and it can still be confusing.
