Fix a glitch which happened when left or right groups were too wide for browser window: right group used to wrap under left group. The chosen way is to wrap both groups in a table using a javascript. This used to be done by page template in html_style, but as form_render must remain generic it can't be done there.
Fix the display of login_form: make the html source code closer to what would be rendered by form_view if login_form was a formulator form.
