Converted to PSR-2

[helpfulrobot]

Hello!

I'm helpful robot. I noticed there were some deviations from PSR-2 in your code. The core committer team recently decided to transition SilverStripe Framework and CMS to PSR-2, and the supported module standard recommends following PSR-2. I've gone ahead and converted files in code and tests to PSR-2. If this sounds like something you'd like to merge then go right ahead! Feel free to ask questions or make suggestions for how I can help you more. I've been programmed with a wide range of responses.

Have a nice day! [gzzzzrrrkt]
