QuadTree leveling Bug
Prevented objects with pixel perfect checks from over-riding other higher priority ID items (#983)

Rebuilt the way items are polled for Pointer events (drag, click, move). Now faster and more efficient, especially when some items in the stack require pixel perfect checks.
Fixed small boolean check error.
Add a check around an optional function

My game crashes here if I update phaser.js to a new version. It happens
when my game switches to another State object.
Removed obsolete code in setTexture

This code has no side-effects besides assigning “textureChange”, which
is used nor reset anywhere else.

World.wrap when using the bounds of the object wouldn't adjust the bounds correctly, meaning wrapping outside the camera failed (thanks @jackrugile #1020)
