    Add ontap

This adds an tap event to an element of your choice.
The tap event is like click, but it works with both mice and touch without the 300 ms delay.
This was inspired by enyojs's tap event.
A side note: When using inline the event object is unavailable and return false doesn't prevent default(onclick).
The idea is to replace click and touchdown events with this one for better performance on touch and less clutter.
