Bug#775445: Review tasks completed (I hope)

[David Buck <buckyballreaction@gmail.com>]

I pulled out roughly 2 dozen review tasks to improve the package and/or 
respect the DFSG.  The result is now posted on mentors as the latest 
package:

http://mentors.debian.net/debian/pool/main/b/bitfighter/bitfighter_019d+dfsg-13.dsc

Some notable changes that were made to the game:
* There is one lintian warning left about checking gpg signature.  Upstream
  does not sign their packages (yet), but contact was made on the issue.
* Menu music was removed because the license could not be determined (contact
  with the creator is still pending)
* The one non-DFSG font was removed and the game was patched to use a different
  font (fonts-play).
* The source tarball was repackaged to exclude many files (like DLLs, etc.) by
  using the Files-Excluded mechanism in debian/copyright

I also ran 'check-all-the-things' against the package and cleaned up several
issues that it found.

Thanks!,
David
