Standalone does not show a help message for <command> -h

[sauterl]

Version: v3.11.+
Standalone Mode (i.e. obtained by ./gradlew distZip then using the dist of module runtime)
OS: Tested with ubuntu 20.04 and windows 10
Command: every command, for instance ./cineast-runtime-3.11.3/bin/cineast-runtime cineast.json extract -h

Currently, if a command is executed with the commonly expected POSIX help option -h, an exception is thrown without further notice.

While the exception mentions what went wrong, this is not a desirabled behaviour. Ideally, the help message for that command is shown and optionally what went wrong with this particular call.
