-Updated CameraModel and StereoCameraModel so that a stereo camera model can be initialization from know intrinsics and extrinsics

-CreateSimpleCalibrationDialog updated to create mono/stereo calibration files with advanced option (setting intrinsics of each camera + extrinsics between them). Rectification R and new camera P matrices are then automatically computed.
-Added GeodeticCoords class for convience conversion between GPS values (latitude/longitude/altitude) to local coordinate (ENU).
-Added support of Malaga Urban and St Lucia ground truths.
-CameraImages: added option to debayer images. Timestamps file: added support of "sec millisec" format.
-Added UException class: exceptions are sent instead of exiting the application on UASSERT or UFATAL.
