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

our CI can't handle it

Now that we have a separate component for keyclaok we can move those
keycloak specific settings into their own attributes.

This should make it more clear what the components are used for

vpu-auth listens to login/logout events which the button emits
and the button shows data from the auth-update event.

Same hover effect, padding and cleanup the CSS etc.

It should only span the whole width in mobile mode

This should make it work in all (LTR at least) cases.

We don't want it to make the page scroll when the display is really small

By setting a max-width on the element it will use ellipsis to shorten the
user name

This reverts commit 1416d0ac942c8bf6f6d52efc03f9f59e6087b2fe.

See issue #9

If the page prevents the default handler in beforeunload the logout
never occurs and we end up in an endless transient "logging-out" state.

Prevent this by reverting the login status back in that case.

We don't want to depend on harcoded values in the build

In some cases we want to set the path via a html attribute where we can't easily
compute a URL relative to the bundle or page. Convert a path to an URL
if parsing it as an URL doesn't work instead.

No longer needed
