As result of moving the "website into the backend" [1], two new entries
have been added in the user-dropdown: one that redirects to the
backend ("Apps") and another one to edit the current page ("Configure
this page").
This commit removes the one to edit, since the same action it's already
in the floating nav (.o_frontend_to_backend_nav) and keeping two
actions would have be redundant.
For the same reason the "Apps" one could have been removed too, but it
has been decided to keep it to ease lambda users' efforts to find their
way to the backend.
This commit refines the design too, adding icons for all entries and
adapting the user-dropdown layout.
