Steps to reproduce:

1. set up a tipsy tooltip with delayIn/delayOut settings
2. quickly enter and exit the element's are with the mouse a few times

Expected result: the tooltip appears at first mouseenter + delayIn, stays visible until last mouseleave + delayOut

Actual result: the tooltip flickers weirdly, as every mouseenter/mouseleave triggers a show/hide event, even if other such events happen before the callback is triggered.
