Fixed
* `Plug` and `Bulb` actions would throw an Exception when requested with time delay 4
* Parsing `LockGateway` devices didn't account for `None` type when parsing child `Locks` 3
* Typos in the code examples for interacting with `Plugs` 2
Changed
* `Device.parse` will now return a generic `Device` object instead of `None` when encountering an unsupported device 1
