Implement #1584 - Fields now registered by their JSON type name, allowing new custom fields and overriding of the standard fields. Replaces the manual switch statement for loading fields from JSON block definitions.
If external code can ‘play’, it should be able to ‘load’. Resolves
compile error in Blockly Games. Feel free to push back if this API
shouldn’t be public.
Also fix compiler warnings on block defs. ‘undefined’ means undefined, ‘=‘ means optional.
Adds `Block.getHue()` to retrieve the block colour when set via a hue.
