fgallery 1.8.2

* Allow to generate a gallery directly on filesystems without hard-links.
* Fix generation failure on BSD systems (use a common set of "cp" arguments).
* Handle more malformed/missing EXIF timestamps.
* Use ``Cpanel::JSON::XS`` instead of ``JSON::XS`` (fixing errors in recent
  unsupported combinations of Perl / JSON::XS and threads).
* New ``fgallery`` man page provided by Guus Sliepen.
