New functionalities: Add filter support & New IOS8 camera features

[YSDC]

Hello,

• Are you planning to add the new IOS8 features like white balancing configurable, etc?
• I've edit your sources to add CIFilter support, let me know if you are interested to add it as an optional attribute (for the moment only one filter at a time but easy to adapt).

Hey there @YSDC.

Don't have any plans for iOS 8 tbh.
Always open to pull requests and happy to discuss details once you've made it.
