combine events

[bzo]

I've noticed that what I would consider one event is often split up into multiple consecutive events. For example, if a person walks into a room, pauses to look at something, then turns around and leaves, this will most likely be captured in at least 2 seperate events.

It would be nice if there was a threshold in which consecutive events were combined. Perhaps if gap between the events was still wholely contained within the image ring buffer when the second event was triggered?
