Rename this.contextRestoredLostFunction to this.contextRestoredFunction

Fix WebGlContextLost handling. ...

In WebGlRenderer.js, this.contextLost was being used both as a function
created by bind() and as a boolean variable. Not only is this
incorrect, it also would cause problems in Firefox when calling
removeEventListener, as it would expect contextLost to be a function,
but instead it would get a boolean and would raise an error. Chrome did
not raise an error when calling removeEventListener with a boolean
value as the second argument instead of a function.

This patch separates the two uses of this.contextLost, which is how it
should be.

Adding support for pooling Point objects in
PIXI.InteractionData.prototype.getLocalPosition

In certain use cases, such as dragging, events are fired off in rapid
succession.

Creating a new PIXI.Point in each event can cause memory usage to build up
and trigger a nasty garbage collection event.

This commit allows you to pass in a point instead of allocating a new one
each time the method is called.

Sample usage would be something like this:

var newPosition = new PIXI.Point();

myContainer.mousemove = function(data) {
	data.originalEvent.preventDefault();

	this.data.getLocalPosition(this.parent, newPosition);

	this.position.x = newPosition.x;
	this.position.y = newPosition.y;
}
