Added Efficiency in Bulk Scoping

Primarily changed how the application "Bulk Mobile App Scoping" applied changes to the app's scope.
Now, when the user clicks "Apply" it will only push the app scopes to scopes that have actually been changed, instead of to all the apps... This also prevents issues or bugs that could occur when we "update" the scope of an app, even though the scope didn't actually change.

Works as expected.

main.py and jamfInterface.py belong to the bulk-scoping application.

These have been tested with Jamf 10.9 and Python 3.7, on Windows and Mac.
