Rename from PickSome to Deliberation
Created by: slifty
This PR changes the labels, filenames, and variable names to use "Deliberation" and "Choice" instead of "PickSome" and "Pick".
NOTE: this makes no attempt to migrate for past installations of the tool. Any site that is currently using the PickSome tool will need to manually:
- Rename the PickSome database to "Deliberation".
- Update the LocalSettings import to import Deliberation instead of PickSome.
Once this is merged the repository should also be renamed.
