Add ability to check multiple roles or permissions in userHasPermission method.

[sptik12]

Currently to check user permissions for several roles we compelled to do something like

function canDoSomething(CurrentUser $currentUser) { return $currentUser->can(Role1) || $currentUser->can(Role2) || $currentUser->can(Role3); }

It will be great of we'll have ability to write function canDoSomething(CurrentUser $currentUser) { return $currentUser->can([Role1, Role2, Role3]) }
