#305 Modularize logic / separate from data classes (wip – doesn't compile)

- Remove permission logic on command side; make PermissionsManager handle checks for all CommandSender objects (not only Player), cf. #314
- Remove unnecessary redundancies in passed arguments ("command references" that can be inferred from the FoundResult)
- Extend FoundCommandResult to represent all possible error cases
