erp5_web_renderjs_ui: keep previous focus color

This reverts commit a87db49b.

Most ERP5 web sites use a global form wrapping the content.
Modify the html viewer to not drop this content.

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.

This gadget take an HTML string as parameter.

It first cleans it up (with hardcoded behaviour currently) by dropping unknown tag elements, unknown/unsafe tag attributes.
It is another protection layer on top of asStrippedHTML inside ERP5.

Then, it displays the output HTML and style it with an hardcoded set of rules.

fixup! erp5_web_renderjs_ui_test: cover case of orange highlight not displayed in rjs_gadget_erp5_emailfield_js with test

erp5_web_renderjs_ui_test: cover case of orange highlight not displayed in rjs_gadget_erp5_emailfield_js with test

store error_text to be propagate to render()

This allows crawlers like wget to also fetch the rendering gadget without executing any JS

This will be needed for DCWorkflow to ERP5Workflow migration so this will be
a core Document and make bootstrap easier.
