Details:

Currently the hash function used to color nicks in the IRC plugin is a simple
sum of every unicode character of the colored nick. 
This causes some problems :
* Two nicks that are identical except some permutated letters (alice and
ailce) will display identically;
* Speaking more generally, similar nicks (alice and alidd), instead of being
visually distinguished by the colors, are more likely to appear identically
and being confused more easily.

Using a hash function with a better randomized repartition (in this case, the
djb2 algorithm) is a way of solving this problem.
