Cudasift tuning and SSC supporting multicameras (#1677)

Browse Source 
* 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
