* Google changed from an Inc to an LLC.
This happened back in 2017 but we didn’t notice. Officially we should update files from Inc to LLC when they are changed as part of regular edits, but this is a nightmare to remember for the next decade.
* Remove project description/titles from licenses
This is no longer part of Google’s header requirements. Our existing descriptions were useless (“Visual Blocks Editor”) or grossly obselete (“Visual Blocks Language”).
* License no longer requires URL.
* Fix license regexps.
Replacing all Closure goog. library calls from BlockFactory, with the exception of the ColorPicker and the test for the warning about running without Closure. This includes (almost) all goog.provide and goog.require statements.
Adding BlocklyDevTools.Analytics, an interface for integrating an analytics
library to track basic usage, including:
* navigation.
* saving, importing, and exporting.
* warnings and errors.
