Remove FAST detector.
Add Moravec detector.
This detector is more suited to tracking since it try to choose patterns which are unlikely to drift by computing SAD with neighbouring patches.
It could be improved to better avoid edges.

Add an uncalibrated reconstruction pipeline to libmv.
Note: The pipeline doesn't actually work yet! It runs, but the resulting
reconstruction is wildly broken. I have a number of theories as to why this is,
and will write tests to track this down, but this change has grown out of
control in the meantime.

Avoid unecessary pyramid copy.
commit 31908b280e8862f15c3f67f697727dd692db9997
Author: Matthias Fauconneau <matthias.fauconneau@gmail.com>
Date: Wed Jul 20 10:45:54 2011 +0200
tracker.cc: Extract float image only when necessary.
klt.cc: Remove retrack which wasn't useful when we already use robust time-reversible KLT (+40% speed)
klt.cc: Factorize bilinear sampling
We are probably limited by bandwidth because of the float image filtering.
Next optimization step would require reducing filter sizes and use integer filtering.
Though, it will be necessary to verify the impact of tracking quality.

Incremental Optimization #4: Keep last filtered pyramid.
This avoid computing the pyramid downsampling twice (as new patch and then as old patch).
API was changed as this require the client to keep our state.
