Title: feat(tooltip): Setting to show only single popup

Can be invoked using:
$tooltipProvider.options({ popoverMode: 'single'});

The code is big, but it's mostly comments.

I think it would be good idea to do this globally (through tooltipProvider). The popover-group
directive is also an interesting idea, but this is much simpler to use
for the end user. No?
