Feature multiple states

[Chaos99]

Adds a second state "members_only" to the script for issue #2

• breaks api (0.13) compatibility, but may be backwards compatible dependent on the client implementation (has to evaluate non-empty string to boolean true)
• more states may be added based on the new scheme
• adds new icon
• adds more information in README
• second state is not yet set in generate_spaceapi based on any input

I'm not sure breaking compat with current clients is the way to go, espacially when there's no newer API version. A well-defined API like the spaceapi is well-defined for a reason, so I'd rather see this in the sections where user-defined things like these are actually supported until the spaceapi is changed. (opened a new issue on their github page yet?)

Breaking API compat might work for some clients, but especially in languages with strong typing this might bekome a real problem(read: crashes, undefined behaviour, etc.) - just because we didn't care to use the API properly :/

Ok. Then lets close this request and start a new one once this is changed in the code.
There is (now ?) more info in the issue description about how to implement.
