re support Opera + api changes + bump to 0.0.4

getting rid of ƒ and add some new helpers:

#API

* Zanimo(domElement) ➡ promise(domElement)
* Zanimo.f(domElement) ➡ function(domElement) : promise(domElement)
* Zanimo.transition(domElement, property, value, duration, timingFunction) ➡ promise(domElement)
* Zanimo.transitionf(property, value, duration, timingFunction) ➡ function(domElement) : promise(domElement)
* Zanimo.transform(domElement, value) ➡ promise(domElement)
* Zanimo.transformf(value) ➡ function(domElement) : promise(domElement)
