This commit add various information in views, like name attribute, to
better handle extension.
It improves also the way the FormViewDialog is rendered in the project
right side panel, we no longer have to call willStart at each insertion
of the Form in the DOM since the form is rerendered automatically by
owl once the state changes.
Some click handlers now prevent propagation to ease the addition of
handlers for further needs.
