* Add new constant QUEUED_EVENTS_BATCH_SIZE to limit events sent once
(related to 31)
* Add "Beats" transport (logstash-input-beats, related to 31)

setting
* Docs: better document the shared database between handlers (30)
* Perform tests also against Python 3.7

* Docs: minor improvements

* Handle possible non-bytes result in Formatter (18, rmihael)

* Implement rate limiting of LogProcessingWorker error messages
* Add a constant to configure the timeout for the Sqlite database

* Call flush on worker thread only if it is running (prevent errors when application shuts down before anything was logged)
* Rewrite utils.ichunked to not raise StopIteration (for future Python 3.7 compability)
