Use the main bundle by default

[arminelec]

The bundle id was hardcoded. However, other projects that are not using CocoaPods, have to use their own bundle id.

That will cause problems for Carthage (using a SwiftR framework). I think we need a change to determine:

1. CocoaPods
2. Framework
3. Source code

Maybe something like this:

#if COCOAPODS
        let bundle = NSBundle(identifier: "org.cocoapods.SwiftR")!
#elseif SWIFTR_FRAMEWORK
        let bundle = NSBundle(identifier: "com.adamhartford.SwiftR")!
#else
        let bundle = NSBundle.mainBundle()
#endif

I have not used Carthage, but this change works for me! :)
