Borkler

Lots of code cleanup and a few bugfixes.

Fixed the "thirsty" setting, which was being ignored in the previous version.

Added a GUI that allows you to see the fluids in the boiler in real time.

Server-friendliness: ticking calculations are no longer done both on the client and the server side. This is a good step towards reducing desynchronization issues.

Implemented automatic steam output. The boiler will evenly distribute steam to all connected acceptors.

Logger level adjusting. Borkler should no longer clutter your log file with pointless INFO messages. Some DEBUG messages might still be there, though. This is intended.

This version is not compatible with the previous 0.1.x versions due to me cleaning up the code and doing stuff the way it was meant to be done - hence, the upgraded version number. Please, remove all boilers from your save before updating. Failure to do so may result in undetermined behaviour.
