Summary0003659: New symbol to read metadata based on CMA hooks
DescriptionImplement a new symbol that can read out metadata (e.g. title, or thumbnail URL) for any given content type and ID.

This allows catalogue templates to pull in more complex data about resources being referenced.

Make sure it doesn't crash if invalid parameters given, or if there's a failed lookup.

Support:
 - title (gets directly from content lookup function)
 - url (gets directly from content lookup function)
 - thumb (gets using thumb_field in CMA metadata)
 - description (?)
 - ... many others from CMA hook (category, views, submitter, author, add_time, ...)

Make sure all data is returned in string form, as needed by Tempcode.

Document the symbol.
Additional InformationA very basic implementation (not doing most of the above specification) as a proof of concept...
