Add id sorting for events, at new lowest weight.
Add id sorting for events, at new lowest weight.

Resolves conflicts between events that occur at the same
time and have the same name.  ID sorting will always return
the same order, but the order is meaningless so it should
always be last to solve conflicts between otherwise identical
events.
