Add Timestamp to the non-debug logger

[j-griffith]

Logrus is cool, but the defaults are sort of annoying, things like no tty having a different format, and Debug having Timestamps by default but higher levels not.

This patch just adds Timestamp explicitly so it should be listed in every message regardless of log level etc. There's lots of room for improvement in our logging but this is at least one samll step forward for reading gophers.

Partial BugFix for Issue: #61
