Add Triclops functions to control Bumblebee2 in Linux

Changes committed:
- Added .ini options for stereo mode control: stereo_mode, get_rectified, rect_width, rect_height
- Added new flycap member variables for storing intrinsic calibration: baseline and intrinsic matrix parameters
- In CImageGrabber_FlyCapture2::open added stereo_mode option to configure camera grabbing with Triclops
- Added new method overloading CImageGrabber_FlyCapture2::getObservation for retrieving stereo observations through Triclops library
- In CCameraSensor::getNextFrame stereo mode is now checked through new method CImageGrabber_FlyCapture2::isStereo(),
and then returns CObservationImage if false or CObservationStereoImages if true
- Minor fix to PGR types conversion tables for adding FORMAT7 recognition in verbose
