Blueprints generated by discovery should show as modified by the name of the user that generated them

[LeeorV]

Currently, when discovering assets in a connected Repository and and generating Blueprints from assets in it, the Blueprints appear as "Modified by: Torque"

I think this should instead use the username (or if available, the full name) of the Torque user that generated the Blueprint.

This is needed for easier identification of clutter in a Space where multiple space admins are generating Blueprints.
