Fixing keyboard commands in the Character sample.
Setting opacity, visibility, and enabled/disabled on a Container now affects the container's children.
Setting control properties now affects STATE_DISABLED correctly.
Text color is now affected by a control's current opacity.
The LightTest was used to test these changes.
