--------------------------+----------------------------------
 This patch updates libpano13 to version 2.9.19. I also indicated that the
 license is GPL-2+ and obfuscated your maintainer email address, which
 should reduce the chance that your address could be harvested for spam
 purposes. I updated the master_sites to [wiki:howto/AvoidRedirects avoid
 redirects] and fixed the livecheck. I removed the configure arg for
 setting the mandir, since the current version of the configure script
 already defaults to that location. I removed configure cflags, cxxflags
 and ldflags that were added to the port a long time ago, which I don't
 think are correct anymore and I don't think they're needed anymore. They
 were added in r72705 purportedly to fix universal building, as reported in
 #25828, but universal building works fine for me without them.

 This update is a prerequisite for updating hugin-app to 2014.0.0.

 This update includes a new library version number for libpano13, so all
 ports linked with libpano13 will need to have their revisions increased to
 be rebuilt.

 If you have no objections, I'm happy to commit this update.
