erp5_core: use the html_viewer when the field is non editable

Stop using ck_editor in read_only to display HTML.

This allows to get rid of the ck_editor iframe, allowing a faster load and removing the iframe scroll.
The maximise button is no more needed in such case.

It also removes all ck_editor links handling: links can be open in another browser tab now.

This changes impacts both xhtml style and erp5js.
