Clean up notify, with watch/message for sprites/maps/data/code task completions.
Add basic skeleton for a time-aware scene/object/view and a TileMap/View.
 - TODO: Add camera, normalize world units and scaling.
 - Add Underscore.JS as a dependency
Render frames independently of object ticking.  Add FPS counter to Scene.
Add World/Screen coordinate conversion utilities to SceneView class.
Update Rect class to add a clipping and scaling functions
Update tilemap and view to support camera occlusion and zooming.
Set size normal.  Fix potential null ref error in button pressing.
Update Scene/SceneView/TileMapView:
  - Support debugRender method on SceneView that is only rendered when the scene has the option `debugRender` as true.
  - Initialize Scene with options object now, to avoid parameter explosions.
  - Detect MSPF/FPS in scene.  Emphasize MSPF which is a better indicator of performance.  Each frame time measurement includes both ticking the objects in the scene, as well as render/debugRender invocations.  As such the output is a measurement of the full time it took to process/render the frame.
  - Fix a number of typos in Point implementation, and alias a scale method that maps to multiply.
  - Add canvasMousePosition to SceneView that converts a mouse move event to a Point that represents the position relative to the Canvas.
Disable tile hover debug render, for now.
Move UI out of core/ and into ui/
Move math utils into /core and remove /math directory.
Remove resource registration functions out of data/game.js and into core/resources.coffee.
 - Registers window.eburp, and 3 resource registration functions that hang off of it.
Move all but gurk class out of gurk.coffee and into game/
 - Move initialization code out into client side JS.  The game shouldn't expose this.  var game = new eburp.Gurk()
Move main game initialization code to the top of gurk class, for better readability.
Cleanup in SceneView
Update TileMapView to scale/follow camera.
Missed resources.coffee (exposes resource registration functions on window.eburb)
Cleanup in rect:
 - Round center/setCenter floating points UP to integer.
Make sure debugRender doesn't crash if a view has no context.
