Shorten and reorganize menu names

Change the left hand side menu designation to be the 'main'
menu from 'sidebar', the menu at the top goes from 'main'
to 'topside'. All menus are referenced by their name only
and the fragment 'menu' is dropped from all as it is obvious
that they are menus and the Menu class doesn't supply any
other kind of object.
