Revision 495362

- Update FLTK to version 1.3.5 which brings many new features,
  bug fixes, and adaptations to new compilers
- Switch to the smaller .tar.bz2 distfile and make a few implicit
  dependencies explicit (as reported by `stage-qa')
- Rename `test/help' demo program to `test/help_dialog' in order
  to unbreak against upcomig `devel/ninja' update to version 1.9.0
- The ABI is 100% compatible with the previous version so no port
  revision bumps are necessary for consumer ports
- Chase HTTP redirection in the MASTER_SITES and WWW: line
