The "Site" menu will now be organized in 3 sub-areas, the last two being
named "Content" and "This page". The first area contains a link to the
website iframe and the menu editor. The "Content" area will contain
menus to list all contents of the website (page, products, events, ...).
This commit only moves the "page" one, the others will be created by
other commits of this PR. The "This page" area contains elements
specific to the page (html editor, page properties, ...).
