new core function 'verifyOptions' .. let's check arguments given to constructors
catch typos and wrong options sent to Sprite()
move tilemap tests to bottom
let's do better then verifyOptions ... parseOptions which inits verifies and inits default options and the same time
use jaws.parseOptions(), new default_options object, rename anchor() -> setAnchor()
API change: sprite.scale -> sprite.scaleAll
scale -> scaleAll
set assets root in core.js
set default_options on object directly instead of on prototype
use parseOptions in Parallax
use parseOptions in TileMap()
default_options belonged to the prototype
use scaleAll() instead of scale()
use parseOptions in SpriteSheet()
move private method to bottom
fix typo
anchor -> setAnchor, add assetsloading
use prototype for default options
more use of asset preloading
split tile map tests to reflect upcomming src-split
