* Implement GH-830: Add coming soon tooltips

This implements coming soon tooltips for:
* the small stage size
* save, load and language

It also creates the component that can be copied over into the paint editor for use there as well.

Lastly, this does a small refactor on the full screen implementation to include multiple small screen sizes too.

Localizes the pen extension:
- loads all pen locale information - may want to consider dynamically loading locales later.

  ** This test was failing because using window.miximize() on the
     chromedriver would hang indefinitely. This seems to be a bug
     introduced in chrome stable 60+. relevant bug report:

     https://bugs.chromium.org/p/chromedriver/issues/detail?id=1901

  1. Updated test to use workaround: setSize(1920, 1080).

  2. Updated test to restore driver to previous size so any unit test
     run after this one will be run in the default browser size.
