Adding a script to assist in deprecation review

Given that the Hydra gem is pegged against specific versions other gems
When we update the Hydra gem and its underlying dependent gems
And we provide deprecation warnings via the Deprecation gem (extend
    Deprecation)
Then we should provide a list of files with a change in Deprecation
And provide some means for a huamn to review those changes
Merge pull request #22 from projecthydra/wip-for-query-deprecation

Adding a script to assist in deprecation review

This is a nice function.  We should also put this in as a standard step when upgrading existing hydra heads... would be very useful.
