* 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.
* Break CSS into modules.
Drops the compile test by 3 KB.
Remove obsolete .blocklyDraggable class stub (it used to be dynamically changed).
Remove unused menuseparator CSS.
Random improvements to require statements.
Removal of some obviously dead CSS.
.blocklyDropDownDiv no longer supresses text selection (see comment in PR).
This PR drops the compiled size by 4 KB, which is larger than I was expecting.
Also removes three private accesses from workspaceSvg into toolbox tree.
The strategy for workspace.updateToolbox is no longer to clear and repopulate the toolbox, but rather to throw away the old toolbox and rebuild a new one. This is simpler and more reliable.
This commit trims off another KB from the compiled code.
This default Closure image was always being overridden and was never fetched. But it takes some research to determine that this is not in effect a potential monitoring point.
Adds the ability to set the tooltip titles for each colour.
Note that Closure’s colour picker in Blockly used to have keyboard controls (as of > 3 years ago); but no longer seems to. This replacement does not currently have keyboard controls either.
Replace the fixed dropdown height with one responsive to the document's viewport.
This is adapted from Bohdan-Tereta's proposed solution:

It is sub-optimal, in that is does not adapt to field height (variable
due to workspace zoom), and it does not fully utilize the space above
or below the field if the block is near the top or the bottom.
