ArAbstractSelect will euggest a matching option if,
an invalid arg was passed & a matching one exists at.
If an invalid subcommand aliases were passed,
a matching subcommand will be suggested.
After feedback from MonMarty a few misc messages was changed.
Now when using tab it should suggest subcommands (if any available) instead of players/senders.

Some plugins (PerWorldPlugins) use a hacky command structure like MassiveCore does.
Their command strcuture aims to limit commands per world.
This will make it a tiny bit easier, so they don't need,
special support system for MassiveCore, and don't have to update it.
Other plugins might also use this, but atleast it doesn't hurt us.
