Title:
  Duplicate file names confuse align_image_stack

Status in Hugin - Panorama Tools GUI:
  Confirmed

Bug description:
  If a project has duplicate filenames, but not files, i.e., pathnames are different, all control points generated by align_image_stack to a set of files with the same name get assigned to the first file of that name.

e.g., if a project has 3 files:
     dir1/image1
     dir2/image1
     dir3/image1

select the three files in the GUI ("Images" tab) and "Create Control Points" using "align_image_stack" CP generator, all the generated CP's will end up in the same (first) image. If the files are renamed so they have distinct file names, they get properly associated with the three separate files. 

Notes: 
1. Haven't tested this with other CP detectors, so not sure if it's an align_image_stack issue or something more general.
2. The motivation for having duplicate names in separate folders is to sets of bracketed exposures in separate directories, 1 exposure set per directory, but corresponding exposures of same image having the same name. This is purely a housekeeping issue, so it's easy to workaround the problem once you know it exists.
