[ADD] web: add state_selection widget tests and documentation

This commit also adds the special_click property which is used to mark
a DOM element such that clicks on it will not be intercepted by the
list view.

Basically, we need this on elements which rely on bootstrap events,
since those need to bubble all the way up. If we catch them in
the list view, to open a cell or a record, then they never get to
bootstrap's level and so the widgets relying on these elements
cannot work.

We plan to remove it at some point, when we have more time to figure
out a way for the click event to reach bootstrap from inside the list
view without breaking the list view behavior itself.
