- Make stage look more like a tile element and not flust with the stage info width.
- Make the stage select state more apparent

The onMouseUp handler for the menu rerenders the language menu before the select onChange function runs on Firefox. So it resets the language value back to the previous value and the locale doesn’t update. If the languageMenu isopen don’t fire the openlanguageMenu action.

Depends on https://github.com/LLK/scratch-vm/pull/1321

Eliminate warnings and errors due to library item text (name and desctiption) being localized components instead of simply a string. Some are not localized (e.g. LEGO EV3), so either string or component is possible.

- Resized the next/prev cards and buttons
- Resized the “Remove” and “All Tips” buttons in the nav
- Added hover feedback on next/prev and nav items

In addtion to changing the UI color for “mini cards” from motion blue to extensions aqua, this commit also updates the color variable previously known as ‘$pen-primary’ to ‘$extensions-primary’.

This is not yet implemented in the VM, but will be needed when it is.

Allow specifying variables as local vs. global. Pass var names from VM to scratch-blocks for checking for conflicts in all sprites when attempting to create a global var.
