[PATCH] [XoIRC] Make default nicks more meaningful (#5385)

[Phil Bordelon]

At last, a non-trivial patch.

By default, XoIRC uses the username when another nick is not
provided.  Alas, for every XO, this is 'olpc'.  This makes for
rather a mess in the IRC channels.

This patch instead generates a more-meaningful nick:

* It takes up to 11 alphabetic characters from the user's Sugar
  nick;
* it appends a hyphen; and
* it adds the last four hexadecimal digits of the MD5 hash of
  the user's public key.

The last serves a dual purpose: it (fairly) uniquely identifies
each XO, and it keeps the collisions to a theoretical minimum
if there are, say, lots of 'jane's or 'john's signing on.

The bug that this patch was originally posted to is at:
