* Use goog.module in mocha tests
* Fix compiler warnings
* Make test helpers a module
* Name test modules Blockly.test.*
This is to be more consistent with how non-test modules are named.
Also remove top-level goog.require of TestHelpers (now
Blockly.test.helpers) since requiring a side-effect-less module does
nothing.
* Convert block_test.js and comment_test.js to goog.module syntax
* Address PR comments
* Goog modulify tests
* Goog modulify toolbox helpers
* Fixes imports and moves common tests from workspace_test.js to a helper file.
* Update test deps after rebase
