#398 Wrap problem in email addresses

[Chris Edwards]

This patch will change the email columns in the
addressbook and addressbook search pages to wrap the
email addresses in the event that a user places
multiple addresses in the email field. This is handy
if someone is using one entry to mail multiple
recipients from a single addressbook entry.

This was something that our users requested since we've
been using squirrelmail (since 1.2.x) but I've never
sent in a patch for this. I've been changing this
every release and figured someone else might like this
change as well for the stable series.

This patch is for 1.4.8
