A few fixes for binding contexts and a fix for the serial controller double starting. This will prevent Access Denied on Windows and possibly other issues on other platforms.

Also implemented a work around for preventing the library crashing when the cameraBuffer is empty on error in Camera. This seems like a bad idea because why is the cameraBuffer empty? Basically ignores the error. Need to figure out why the cameraBuffer is empty to handle this properly.
