Fixed bin/fetchware not being indexed by adding missing shebang line.

Maybe that will do the trick. I though it was dzil that adds this, but dzil does
not touch it. Instead, Module::Build or ExtUtils::MakeMaker does this for you.
That means that I need it to have a shebang line in the script, and the build
scripts will just update it to $^X during install.

    * Attempt to fix bin/fetchware not properly being indexed again :)
      bin/fetchware was missing a shebang line. This has been fixed. Perhaps
      this is the snag preventing bin/fetchware from being indexed properly.
