Add support for v3 binlogs

[sindrehan]

Since Blunux v3.0.47 all new logs are stored in a protobuf encoded binary format. These logs are listed at http://192.168.1.101/logs instead of the old http://192.168.1.101/logcsv.

The Logs class needs to be altered to check both endpoints, and since the logs-endpoint does not return the initial timestamp for the logs in the json response, so we need to rework the formatter as well.
