#1 hide graphical emoticons (user setting)

[Joris Bontje]

This patch gives the user the option to hide the
display of graphical emoticons in all messages and
postings.
this option is under Settings -> General

I am not entirely sure if I did it the correct way,
maybe the user_id to user to get_pref isn't done
efficient, but atleast it works (for me).
