feat(core): add option to hide existence of not-permitted commands

[jpenilla]

Adds an option so that when the sender is permitted to use a following or preceding node to the one parsed, an invalid syntax exception is returned instead of no permission. Maybe this option should also convert other no permission exceptions to unknown command? Or users could do that via the exception handling system.

Should this be expanded to invalid sender exceptions as well? (probably)
