Since all of our other tools are now using GLI, changing things so this does as well.

QA Plan
-------
Try running the scripts locally.  I was calling the bin file directly doing `bin/op`, but if you bundle, it should add the `op` command to your path.

I have tested out a decent number of these already (this PR was created using `pull-request`), so just confirm that the rest are working as expected.
Yeah, basically it was for convenience.  Normally the `include GLI::App` would get passed in from the `bin/op` file and the scripts didn't need it, but when you run the tests, it is required.  This was to avoid writing `require 'gli'` and `include GLI::App` in everyone of the scripts.

I think in the future, it probably makes more sense to put the `GLI` specific stuff in their own files, and then still have the classes be just ruby objects, but that seems like it is going to have to be a refactoring effort at a later date.
