Finally fixed bug #125864:

* app/core/gimpimage-guides.c (gimp_image_find_guide): iterate
over the entire list of guides to determine the closest one.

* app/core/gimpimage-snap.c: use gdoubles instead of gints for
dist and mindist variables to make sure grid and guides with 1px
spacings work as expected.
