Right now neither are used (get_participants does not have any event listeners anywhere), however in the future it will be easier to convert code that uses the old, nick-based functions.
Templates are still applied on game start according to
var.TEMPLATE_RESTRICTIONS, but now any arbitrary role can be applied as
a template during gameplay without breaking things horribly.
Speaking of breaking things horribly, things are probably broken
horribly due to this. It was lightly tested, but there's a lot of
fundamental stuff that changed.
