Remove the menu-bar, tool-bar and scroll-bar from the UI since I
don't use them at all.

Before doing anything else I should make sure that both the
directories /usr/local/emacs/share/emacs/site-lisp and
/usr/share/emacs/site-list are included in load-path, along with
their subdirectories, but only if they haven't already been added
and exist. Place them at the end of load-path so they don't mess up
package precedence.
