all: add trk: prefixes to possibly evil connections

Prefix URLs to Google services with trk: so that whenever something tries to load them, the developer will be informed via printf and dialog about this infraction. If you see such dialog, we know that (a) either the URL needs to be whitelisted, or (b) the feature that triggered it needs to be disabled by default.
