Understand and implement Click Events from 1st Touch

[Philzen]

See #21

Can also be observed in https://github.com/Philzen/MultiTouch-Browser when checking "polyfill all" in the menu and then doing some random browsing.

default html elements click doesn't work any more then.

Need more understanding how most phones generate click event (presumably 300ms after ontouchend) and implement this in wmp.js, preferably with an option to set the delay.
