* Beginnings of a JSON block definition unit test set.
* Dispose of unit test workspaces and blocks in finally blocks.
* Clarify JSON error message by echoing arg notation.
- Remove unnecessary code and functions.
- Add documentation where needed.
- Fix a bug arising when a block on the workspace is attached to an existing link.
Replaces old colour block definitions with a Blockly.defineBlocksWithJsonArray(..) call. Generator unit tests continue to load and pass, signifying compatibility with prior block definitions.
Replaces extension 'math_number_tooltip' with the reusable 'parent_tooltip_when_inline' extension, also used by colour_picker. Includes tests.
* Add ability to add a class to a scrollbar so that different types of scrollbars can
be distinguished from each other. You used to be able to do this by looking at the parent
element but now all the scrollbars are siblings in the dom.
Also, use this new class to fix#816 so that layering of the flyout and workspace scrollbars
are done correctly.
Adding support for extensions, functions that can assist with loading blocks, much like init functions, but that can be referenced from JSON definitions. This allows JSON definitions to define dynamic blocks such as onchange handlers and mutators.
Rewrote math_number as an example pure JSON block.
FieldNumber and FieldAngle previously accepted "undefined" as values, if not defined in JSON. This catches these and uses "0" for any NaN value. The constructor value parameter is now optional. Includes tests.
This will be used to define constants accessible in JSON block definitions. Messages with descriptions that include `{{Notranslate}}` will not be included in the translation files sent to TranslateWiki. Instead, they are written to `msg/json/constants.json`, and later merged back into the `.js` files, similar to synonyms.

Adding support for string table lookups in dropdown field labels specified in JSON.
Adds Blockly.utils.replaceMessageReferences() method to handle string replacement without interpolation tokens. Effectively uses the same old code, now moved into tokenizeInterpolation_(), which takes a parseInterpolationTokens option.
Replaces the direct JavaScript references (not pure JSON, and thus not portable).
Demonstrating this behavior in the logic_boolean dropdown.
