Added a getter overload and a NodeCollection version of .offset().
Also had to fix .css() for this.
Renamed $.create() to $.elem() to better indicate the method's functionality.
Moved .attr(), .prop(), .removeAttr(), and .removeProp() from HTMLElement.prototype to Element.prototype.
Back to the 2nd HTMLElement#empty() method.
Turns out it is the fastest way: http://jsperf.com/clear-els/2
Version bump to 0.7.0
