if you fail to provide a subcommand this parameter will be passed to the 'main' sub-parser causing it to fail with an error.
run locally (on windows)
'python -m openage --add-dll-search-path <valid_path>'
and see for yourself.

you should get the following error
'openage main: error: unrecognized arguments: --add-dll-search-path <valid_path>'
which is pretty confusing.

This change stops an error from occurring and invokes 'openage main' as if no arguments have been passed.

ah, then the proper solution is to add this as a common parent to the subparsers that make use of the option. duplication is not the proper way, unfortunately.

@TheJJ i've went a slightly different, route see changes.
