Currently, the server runs on Java 8 and some plugins, notably Terrain Control depend on a version-specific hack. Now, we do want to drop TC anyway to upgrade to 1.14.4 but there's also the goal of sharing this plugin for others, who likely run Java 8.
It took me a while to figure out how to make it work with Lombok - have to use the right order.
Fixed default command handler not being overridable in some cases
Schrestart now takes seconds as param, not ticks
Allowing to change the current timer value in the restart event
HelpText support added
Automatically generating usage text (ButtonProcessor)
