[PATCH tooi] EventList: limit size of the list Export this patch

When prepending items to the beginning of the list (which happens when
loading new statuses), limit the size of the list to self.MAX_LENGTH to
prevent it from growing forever.

MAX_LENGTH is currently set to 1024, which should be more than enough
for most users.

This doesn't affect scrolling backward through the timeline: events are
only removed when the timeline is refreshed.
