Canvis a "Freeform Assembly Social Links"

Is your feature request related to a problem? Please describe.
On the assembly show page are social links (twitter, github, etc.). It would be nice if these were more freeform. So an assembly could specify their own links (eg. their website).

Describe the solution you'd like
One or multiple additional field(s) for assembly administrators to define.

Does this issue could impact on users private data?
I don't think so.
