Unix Time Updates.

This removes the `time` trigger from `UnixTime` as requested in #607.  It also updares the output to show the epoch as used and the time which results which is vaguely more useful.
I love Anonymous Pro, my editor font of choice :)  -- but I don't think many people have it installed? Should probably just use `monospace`? I'm not sure what our font-stack is in general for fixed-width fonts.
