v1.01 RoomBooking system released

So I admit that’s a pretty quick release cycle, but hey, I was inspired (or something). There’s some massive changes, most noticeably the addition of user authentication, roles, permissions, logging & password resets. All documentation has been moved to https://github.com/neokoenig/RoomBooking/wiki, where you can find a breakdown of all the settings, permissions, roles and upgrading instructions.
