Webmail goes AJAX

Hello,

I've added in CVS some code bringing AJAX to NSWM. Well, actually, behind 
buzzwords, there's not much. 
I simply plugged in the send mail form a tool that allows email address 
suggestions based on email addresses that are in sentmail logs. 

I've been using it for a while, and it seems to work quite well. Feel free 
to test and comment ! 

Also in CVS, a script that allows to quick search through the mail inbox. 
An input form entry is added to the inbox listing. You enter text to 
search, press "Enter", and it searches for that text through the headers 
in the mails, giving you the list of matching emails. Actually, i'm not 
sure yet if that search interface is ergonomic enough... Feel free to test 
and comment ! 

C u,
Alexandre
