Version 0.17.0

Significant improvements in reconstructing images with perspective projection.

• Switched to 7-point algorithm for detecting the Fundamental Matrix
• Optimize Fundamental Matrix using Levenberg-Marquardt least squares
• Match keypoints using ORB descriptors instead of using cross-correlation
• Use focal length from EXIF data to create an accurate projection matrix
• Use analytical formula for rotation matrix (and switch to Rodrigues' formula)
• Several bugfixes in sparse bundle adjustment significantly improve the end result (SBA finally works now!)
• Sparse bundle adjustment runs several times faster, without using additional RAM
• Detect and discard backprojected points
• Improved outlier filter
• Create interpolated meshes for SFM (more than 2 images)
• Windows version no longer requires the Visual C++ Runtime
• Reduced the binary size
