Add more content so it can be used to test scrolling and activity switching

Add a scope so we don't have to care about naming conflicts
and set the verison to 0.1.0 since we don't have a stable API yet.

Now that we have clearer separated sections in responsive mode the different
spacing stand out so unify them a bit.

Also in case the menu is in sticky mode it's kinda small and hard to hit via touch
so add some padding there and remove some margin from the headline instead to keep
the overall height the same.

Activate Matomo logging only after user logged in successfully. Deactivate if user logs out.

It's no longer used.

In the common case of the user just targeting an activity and not
browsing the menu the user wants the menu to be gone right away.

So it doesn't conflict with screenshotting for the docs

Group activity names and descriptions so it's mroe clear what belongs together

No longer depend on env.js to select the right config but require it
to be passed explicitely in the attributes.

This reverts commit 299dfdded2b3a56a9e666e70c301c7408e570eba.
