-----------
EventListenerMap's m_entries vector wastes a lot of vector capacity

Reviewed by Mark Lam.
EventListenerMap's vector wastes capacity, since it allocates 16 slots but uses
on average 1.63 of them; most contain only 1.
So set the initial capacity to 4. This saves about 54K on nytimes.com. It
measures as perf neutral on Speedometer.
