* 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.
* Add Blockly for the Web codelab code
* Adding licences and comments as per review
* Renaming a4/b4 sounds to a5/b5
* Define blocks with defineBlocksWithJsonArray istead of jsonInit
