added FullPageAdmin, still need to find a proper name for this
instead of adding a new admin class, simply update the StaticContentAdmin to embed Routes and Menu.
Merge branch 'master' into full-admin-example
accidentally moved a little bit too much
proper indentation, correct oder
cascade persist routes and menus
added comment to explain why we still have "setRouteContents" and "setMenuContents"
clean up comments and order of imports
Merge pull request #27 from symfony-cmf/full-admin-example

[WIP] FullPageAdmin
