See issue #31

We no longer bundle keycloak-js with rollup so we can remove those
special cases.

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

Instead of hardcoding the paths of the node_modules directory we use the node-resolve
plugin of rollup to find the root of the corresponding JS package and calcucate a path from
there.

Resolving a package requires calling an async function, so we have to use await in the rollup config.
Luckily rollup supports configs wrapped in a promise, so we just have to wrap it in a function which returns
a promise.

This way we don't have to mirror the directory structure in packages
which vendor this package.

rollup builds the demo, everything else just gets the web component
