This commit changes how the ThingParser is used throughout the code base. Instead of blindly filtering out null values, we're now throwing a new InvalidThingInputString exception. This exception is caught in an outer scope that has more context. The exception is then unwrapped and rethrown as a ConfigError with the additional context. In the outermost scope of (re)loading the config-file, the ConfigError is caught and printed, and then (re)loading stops gracefully.
We still need a proper way to handle loads/reloads consistently to get rid of the default command usage message, but this is a good step towards better usability in the face of user errors.
Fixes#478
This commit adds a new per-arena setting, join-interrupt-timer, which, when set to a positive number, will introduce a delay to the join and spec commands. During this delay, if the player takes damage or moves more than one block's distance, the command will be interrupted.
Closes#482
This, along with a (currently not committed) script to generate github releases and Spigot/DBO formatted release notes from this changelog, should reduce some of the friction associated with new releases.
