remove Alert component

There are a lot of unknowns and context dependendant questions to
implement Alerts in a good way. The current Alert component just had a
role set, and it had no JS attached.

We will revisit this, once we start working on Alert Dialogs,
Notification center notifications (dismissable, hide after x time, ...)
