add a Contact column

[nusenu]

It would be nice to see the (truncated) ContactInfo string on some pages.

• family level, example: https://yui.cat/family/4C5B8134341E66CB09246985E4039F9BFC0ADCE3/
• ASN level: example: https://yui.cat/as/AS42730/

a few ideas to get ContactInfo visible on the table:

• truncate it to 50 chars
• remove the Platform column in favor of ContactInfo
• condense the ASN into the AS Name column by using "name (number)" example: "OVH SAS (AS16276)"
• make the Running column as condensed as on atlas.torproject.org

My interpretation of this issue was to make contact uniqueness available on list pages which I think is achieved by f0c466a. I have a strong preference for table tidiness and using the 8-character hash seems like a happy medium between data availability and cleanliness.

If there's a good reason to prefer the contact string over the hash I'm open to a styling overhaul to support it.

The use-case behind this issue is: "Is there any contactInfo (style) similarity on these relays?", which is something the current implementation does not allow me to see because it requires to move the mouse over each row, therefore it would be nice to have a (truncated) ContactInfo visible on the page.
