BC Break: Dwoo::isArray had to be fixed and it has been split up in 3 methods, isArray (for array access), isTraversable (for foreach) and count (just a helper that counts anything). It won't affect you unless you built some plugin depending on isArray, in which case you should check all works fine still
fixes #37
