Possibly fixes #511
Problem:
Users often define routes in the admin namespace
that they don't want to show up in the sidebar.
At the moment, Administrate creates a sidebar link
for all routes in the admin namepsace,
without a way to ignore them.
Solution:
Add an administrate: false option for dashboard routes
that will prevent Administrate
from creating a sidebar link for the resource.
