Cudasift tuning and SSC supporting multicameras (#1677)
* CudaSIFT: filter doubles * removed fixed threshold * SSC can be used with multicameras. Refactored CudaSIFT to support SSC. Add new parameter SIFT/MaxGaussianThreshold. DbViewer: show negative features with gray color (so that we can know which features are in the vocabulary) * Added SIFT/MaxGaussianThreshold parameter * Updated parameter description
