Added a way to fetch all people from trogdir that are currently in the db and refresh their attributes with the ones that are current in trogdir. Does not affect sync status or remaining syncs
Merge branch 'master' into fetch_all_people
Added update_from_trogdir method to person model and controller and implemented it on the persons show page
Changed policy for update_from_trogdir for person so that it mirrors update permissions
refactored syncinator fetch_all_people method so that it uses fetch_person
Only showing update_from_trogdir link if the current user has permissions to edit.
Only showing link if the persons trogdir ID is present
altered non-id catch notification
Added a logging option to TrogdirSyncinatorWorker

Before it was always logging. Now logging is off by default and you
have to pass in the `{log: true}` option when initializing
`TrogdirSyncinatorWorker` to turn it on
Added test for new update_from_trogdir method

This is testing the new method in `PeopleController` to make sure it
actually updates the person from trogdir.
