Add config_supportAutoRotation.

On some products, it may not make sense to use the accelerometer
to perform auto-rotation.  In that case, the product's config.xml
framework resource overlay should set config_supportAutoRotation
to false.

Setting this to false also disables auto-rotation settings.
