Daniel Drake ba24c0884a Rework some image handling; add public binarization API 
I want to offer the ability for an application to view a binarized
version of a scanned print. This lead onto a few changes:

 1. Store minutiae and binarized data inside fp_img
 2. Move resize code to the capture path, it previously happened much
    later.
 3. Add fp_img_binarize() to return a new image in binarized form.
 4. Add a BINARIZED_FORM flag to prevent an image being binarized again.

In future, it would be nice to be able to binarize without detecting
minutiae, but this involves some work on the NBIS interaction.
