IPv6 peer IP's are written out incorrectly

[spiritualized]

When users are set to be visible (i.e. their IP addresses should be saved to the peers table) there's an issue with IPv6 peers. Ocelot attempts to write out a urlencoded string of the IPv6 IP.

In addition, the default schema defines the peer table's ip column to be of type VARCHAR(15). This should be changed to 39 to accommodate an IPv6 IP of maximum length.

FYI the README clearly states that only IPv4 is supported.
