[IMP] web: restore scroll position

This rev. improves the way the scroll position is restored when
coming back to a view (e.g. open a kanban view, scroll, click on a
record to open it in a form view, go back to kanban using the
breadcrumbs):

 - generalize the scroll position handling from web_enterprise to
   web to make it available in the community webclient as well
 - also restore left scroll position, not only top (especially
   useful for grouped Kanban views with a lot of columns)
 - handle the case where the scrolling area is a sub element of
   the view (e.g. the grouped Kanban view in mobile).
