Add time to issuerReputation and baselineRequirements (fixes #39)

@mozkeeler I could use another pair of eyes on this. aa7fa0a664f428a25cc68923c842edb0b9a477c4 changes the index of the hashmap of issuer reputations to include the truncated timestamp, which is causing a breakage that I can't figure out.
Is it not finished on the next line? (sorry about the tab expand thing -- I thought I set my vimrc not to do that)
