Phaser.ArrayList is a new iterative object, similar in principal to a linked list but operating on a single array without modifying the object structure.

Input and Pointer now use the new ArrayList instead of a LinkedList, which resolve list item removable during callback issues.
Input.reset no longer resets every interactive item it knows of, because they are removed during the destroy phase and can now persist between States if needed.
