Title: Report unknown connection speeds rather than the assumed high value.

Slowly getting to the bottom of this weird reporting. We weren't explicitly showing users who don't support the nav timing API or the connection API. This will be a nice (if disappointing) metric to understand.

This change allows getConnectionSpeed to optionally report unknown speeds so Omniture can query this.
