Title: use logstasher for logging instead of lograge

`lograge` throws away a lot of useful information; this change
would bring signon in line with other applications in the stack by introducing `logstasher`.

**NOTE**: This is an alternative to #86; if one of these is merged, the other should be thrown away.
