Set selected status to sidebar elements

Browse source 
ARIA-selected only works on specific elements/roles. I tried several
combinations here, the most fitting seemed to be the option role, but
that role did not work very well in FF with NVDA. It also should only
be used as direct child to a listbox e.g. with several children.

The next role that's working with ARIA-selected that seemed fitting
is the gridcell. It's still a bit hacky but works well in IE and FF
with NVDA. I suspect that that's pretty good coverage already then.
