Improve consistency with other bt5.

Active process detail is a list of strings.

Even in case of 401 HTTP code, IOS Safari caches query result, and so, prevent user to get result after being logged in.

Force no-cache header if the Hateoas rendering script does not explicitely request cache configuration.

It only display the user's title for now.

Rewritting the header means removing the submit button from the DOM, and losing the submit event.

Example:
* modify an input value
* click (with the mouse/touch) the Save button
* browser with submit 'change' event on the input and 'click' event on the button
* if 'change' event is triggered before, it will lead to the header rewrite. The 'click' event on the button will lead to a form 'submit' event, which will not be catched by the gadget, as the form is already outside the DOM

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

set:
- acquire_local_roles: 0
- content_icon: folder_icon.gif
- meta_type: ERP5 Solver Tool
- factory: addFolder
- filter_content_types: 1
- translation domain erp5_ui to title and short_title

This allow to update the page title and to get the new form rendering, based on tales expression

In case of HTTP error 400, rerender the page with the new JSON returned by ERP5.
