friendlist integration module

Issue Summary

I created a simple module that brings friendlist and coheren access together. It overrides the autocomplete user form element and gives a select list of friends from the friendlist module in place of it. If there is any interest, I am willing to post it, but I think it should be integrated with coherent access. Also, friendlist is being actively developed and I am waiting for a function to be part of their core to simplify my module; I am using my own function for now.
