`CmdrHandler` doesn't automatically give permissions after assigning them to ranks / roles.

[Mophyr]

Using CmdrHandler:GiveRobloxGroupRolePermissionGroups() or CmdrHandler:GiveRobloxGroupRankPermissionGroups() assigns permission command groups to specific roles / ranks.

It's expected that just calling those methods would automatically assign the permission groups to the joining players, as long as they have the associated role / rank, but that doesn't happen and the user needs to also call CmdrHandler.PermissionHandler:GivePlayerPermissionGroups() in order for commands to be usable.

There's also another issue which is the usage of roles themselves to give permission groups. That is because when calling Player:GetRoleInGroup(), it's returned the player rank instead of the role, for some reason. So since that isn't supported yet, I've added an error when trying to use CmdrHandler:GiveRobloxGroupRolePermissionGroups(). Once that has been fixed by Roblox, this should work as intended.
