Timeout for marker mouseout

[davidcalhoun]

It would be really nice to be able to specify a timeout on labels, so they don't close immediately after mousing away. This can be done with a setTimeout, and a clearTimeout for the case when there shouldn't be any delay (such as mousing directly over another marker).

Example:

marker.bindLabel("Test marker!", {
    closeDelay: 500  // 500 millisecond delay after mousing away before label closes
}).addTo(map);

Sorry I'm not very keen on this idea. You could make a fork, add the functionality and then if this gets enough requests I'll pull it in.
