Investigate adding dedicated "Art" links field

[Meorawr]

Not sure what shape this would necessarily take, but would be good to have something a bit more structured as this is quite a common thing people put into their descriptions.

Current thinking is a new field (MSP identifier TBC) that acts as a list of URLs with a short descriptive text for each - so one could envision sending it as newline delimited \[Descriptive Text\](url) style markdown links.
