updated for rubyzip 1.0.0

With the release of rubyzip 1.0, some class names changed. This addresses those changes.

I've updated my Gemfile to pull the latest version of this gem and I now get this error on Heroku (but not locally): uninitialized constant Zip::OutputStream:

Try pulling the latest version of the passbook gem..... 3.1

FINALLY figured this out.

When I ran ruby app.rb, everything worked fine, but when I ran bundle exec ruby app.rb (i.e. I ran using the exact same Gem versions that heroku would use) it didn't. I updated passbook, but things still didn't work. Turns out I needed to remove gem 'zip' from my Gemfile and just include gem 'rubyzip'.

I've tried so many changes in the last hour I can't say with certainty that gem 'zip' was the sole cause of the problem, but removing it was the final step that made everything work.

cool.....it was beginning to sound like that....we needed to update the rubyzip anyways, so that was a good excuse to get that done :). Let me know if you have any other problems etc....
