Github issue #22: Parent transforms, pt 1

Commenced updating codebase to deal with inherited transforms properly.
This commit updates and nominally verifies the basic Matrix and
Transform objects, the CanvasRenderer, and all four renderable
Entities: Sprite, StaticImage, TileMapLayer, and Textfield.

Next commit should test boxes, debug data, and physics; and be followed
by WebGL renderer and WebGL Particle Plugin tests; before final
compatibility testing and sync.
Github issue #22: Parent transforms, pt 2

Corrected Kiwi.Geom.Transform worldX, worldY functions, which were
broken because of changes to Matrix.

Minor efficiency improvements to Kiwi.Components.Box.
Github issue #22: Parent transforms, pt 3

WebGL rendering system overhauled to work properly with updated
transform code.

This is mostly just taking out references to offsets that are now baked
into the coordinates.
Github issue #22: Parent transforms, pt 4

Housekeeping pass: fixed matrix calls in Camera, Textfield and
Transform. Matrix operations and parent-child transform relationships
should now be correct across the board.

Package version for v1.0.1 branch updated to 1.0.1.
