Closes #408

test@127.0.0.1> host find -name "testhost12(3|4)"
Name                 Contact                           IP                         Comment
testhost123.uio.no   user@example.com, alt@example.com 192.0.2.123, 2001:db8::123 A long comment goes here!
testhost124.uio.no   user@example.com                  192.0.2.124                

Standardizes on a consistent format for multiple values (contacts, ips), also fixes existing max contact length calculation for hosts with multiple contacts.
