New Camera Branch with first Driver

[andrewsg3]

First draft of camera. May require integration with the wider system. Documentation present and have tested every listed function.

For testing, I would recommend:

instantiating a camera object trying a livestream() on your laptop or raspi with gui enabled saving a picture with savepicture("filename.jpg")

added Resources/ folder in peripherals containg HAAR cascade xml. you can run it with Camera.greenCascade(cv::Mat image);

Camera code was accidentally committed before, I'll merge this and test and create new issue with bug tag if there are any problems with it.

Ok. Apologies for the accidental commit.
