[Feature request] Home page refresh when exiting book detail

[darthmooguy]

Desired behaviour: When exiting the book detail screen, the home page should be refreshed to update the current book's state (read, unread, in progress with the correct progress indicator, etc).

Current behaviour Currently, when a book passes from the unread to in progress state, when the user exits the reader and the detail page the book is still shown as unread. The home page is only updated when changing sections in the side bar.

Thanks for the cool app frameset, and congrats for the App Store publication! :tada:
