Edited and deleted elements now also get updated in the database. When editing or deleting a single element, it won't update in the map; need to fix

Took gameID from GameList to UserMap. Updated sendGeoJSON and fetchGeoJSON to new back-end somethingwhatever. Updated old code that draws elements under FeatureGroup in DrawTools that have been fetched from database. Added functionality to send circle radius and textbox text to database. Started working on textbox as a React component. Reminded myself to make smaller pushes and merge requests.
