Our router has a prefetch method that accepts an href argument. However, other route-related methods accept a href and as argument.

This pull request unifies the router interface by allowing the user to pass href and as, like they would to other methods.
It also adds optional options to the end, allowing users to specify if the fetch is priority or not.

On mouse enter, we trigger a higher-priority loading of the page by injecting its <script> tags. This makes the files immediately jump to the front of the Network queue, and starts the script parsing early (prior to navigation).
