Use drupls permission system to enable utility bar + code needs clean up

ADD utility_bar_perm(): adds the 'access utility_bar' permission
CAHNGE utility_bar_admin(); remove $form['utility_bar_display'] and $form['utility_bar_display_anon']
CAHNGE utility_bar_init(): use user_acces(). I guess there will be no performance hit, because user_acces has a static vars cache and I am sure it will be called also by other modules hook_init.
ADD utility_bar_update_6001(): to set permissions
REMOVE utility_bar_preprocess_utility_bar(): no need for an empty function.
REMOVE _utility_bar_display_utility_bar(): no need for this: in the js thevariables 'display_anon' and 'user_logged_in' aren't used and the visibility is done by user_acces('access utility_bar');

Less related changes:

CHANGE utility_bar.tpl.php: use utility_bar_messages_header instead of wh_utility_bar_messages_header
CHANGE _utility_bar_container(): if (1) is alway true.
REMOVE $Id$ Tags
REMOVE define(): None of them will be used anymore
REMOVE Whitespaces

I tried both versions of ub 6.x-1.0-beta3 and 6.x-1.x-dev. Both are working.

download the patch to the modules folder, cd in utility_bar and try:

patch -p1 --dry-run < ../utility_bar-permissions-1268606-1.patch
