Also moves core.Key to label.Key, but leaves the implementations behind for now. After using for a while, the word Tag conveys slightly the wrong concept, tagging implies the entire set of information, label maps better to a single named piece of information. A label is just a named key/value pair, it is not really tied to the event package, separating it makes it much easier to understand the public symbols of the event and core packages, and allows us to also move the key implementations somewhere else, which otherwise dominate the API.
