Title: Reworked positioning system to include parenting and additional offset methods.

Changes to UIObject, IPositionable and UISprite was needed to make this possible.
Option to auto refresh position when scaling an object.
Auto adjustment of anchoring when parent changes is implemented.
Centerizing a sprite is taken into account when positioning.
Removed positionCenterX and positionCenterY from position extensions as they no longer made sense in regards to the newly introduced methods.
