Description

Re-implement the tag "display name" attribute found in v9.4 and below.

Solution

Since display names were previously built using the top-most parent tag under JSON, and #332's schema didn't account for this ordering requirement, the tags table will need a dedicated new column to reference the parent tag intended to be used for the display name. A frontend change will also be required in order for the user to select which tag to use as its preferred display name. In the end, this should allow for a much more friendly and flexible system than the one present in the JSON library.

This change will increment the DB_VERSION.
