Move objectIndex.json location into editor appdata #198
Description
Whilst objectIndex.json works perfectly fine on its own, if the user selects a location that requires priviledges, such as a Program Files directory, then the editor needs to be run as admin/root because it needs to write the objectIndex.json file to that folder. The editor should never be run as root/admin, so we should instead store the objectindex.json file in the appdata folder for the editor.
Additionally, if the index was reworked so that one json file stored multipe folders, this could have an additional benefit that a user could search all objects over ALL of their local folders/indexes, not just the current folder they're in.
