Single Type Limited Access UX Experiments

Bookstack has some predefined roles, but roles can be created such that they have read access limited to:
Books
Chapters
Pages
Interface for users with read permissions strictly limited to those types changes dynamically.
See: https://github.com/BookStackApp/BookStack/issues/1171#issuecomment-446378261
They do appear to all have access to the page set as the landing page.
