Add ItemInfoExtractor Agent

[Jascen]

This Agent allows the User to export a bag's worth of items into a CSV format onto the User's clipboard.

This uses minimal server calls (it assumes the Server will return OPL information for every item in a bag when the bag is opened).

By formatting the data in a CSV format (columns are property names), the data is immediately consumable by "basic" users who wish to review items they own. This standard format also allows downstream applications to ingest the data and provide the user a more feature-rich experience.
