Added GPUImageVideoCamera and GPUImageStillCamera

Hi, thanks for the amazing groundwork on the bindings for GPUImage. I added some more bindings and tweaked the existing ones a little. I'm not finished working on it yet but you might want to have a look?

 * added missing binding for GPUImageVideoCamera and GPUImageStillCamera
 * added QuartzCore as mandatory framework
 * fixed bulge filter property bound wrong
