Updates to handle textureless scenes during capture.

1) Starts stitching only when the camera sees a textured scene at the beginning.
2) If a texturess scene is encountered in the middle of a capture, the stitching continues with the intermediate frames translated using the pan velocity estimate.
3) Added more error codes and percolated them up to the java layer.
4) Fix a build error in Mosaic::addFrame() and added comments.
5) Update the javadoc in Mosaic.java to reflect the new returning codes.
