[ptx] hugin 0.5 beta 3 released

[Pablo d'Angelo]

Hi all,

hugin 0.5 beta 3 has been released, you can find the sourcecode and 
win32 executables on http://www.sf.net/projects/hugin

Changes from 0.5 beta 2 to 0.5 beta 3

- Support for cropping (only when using PTStitcher).
    It is possible to attach the crop to the d/e values,
    so that it will be recentered when optimizing d and e.
     Works quite well for my fisheye images.

- proper EXIF reading for rotated jpeg images
- possiblility to optimize and stitch only a subset
   of all images in the project
- some layout fixes.

ciao
   Pablo
