Tweaks : doubleclick_on_library_view

I noticed there's a new(ish) option - show_book_details.

I tried to use it in the enter_key_behavior setting

However, instead of showing the book details popup for the currently selected book it opened one of the format files - I think the first one it finds, an error if there's no format file.

Thinking it might be shortcut entanglement, I set enter_key_behavior back to do-nothing and it was back to taws - i.e. Enter does nothing.

So, I tried it in a fresh install of portable - same deal, if I set the enter_key_behavior to show_book_details the Enter key will open the first available format.

I'd actually like a slightly different option show_book_details_locked.
