[WIP]: Added ReactiveCocoa-fied API Calls

[czechboy0]

Now all public API calls can be asked for a SignalProducer instead of just calling it immediately and passing a completion block.

Example

When getting the names of your bots, in addition to the existing call

server.getBots { (bots, error) -> ()
    if let bots = bots {
        print("My Bots: \(bots.map { $0.name })")
    }
}

you can instead call

server.getBots()
.map { $0.name }
.start(Event.sink(
                error: { print("Error: \($0)") },
                next: { print("My Bots Names: \($0)") }
            ))

Waiting For

• Swift 2 ReactiveCocoa/ReactiveCocoa#2189 Being merged and there being a Podspec with this Swift 2 version.
• Creating some tests for this (might be a good opportunity to start Use Nimble for test matchers #105)
• Add this target to the main scheme so that it gets tested
• Fixing podspec to add RAC as a dependency to our RAC subspec

@czechboy0 example you've provided doesn't look like RAC can bring something better 😜 We need to find more hardcore example 😁
