Title: Crash when switching mode + other fixes

1. When switching file manager mode from restricted (formerly known as "Beginner") to unrestricted (formerly known as "Expert" or "Advanced") and paging down the file list KPV would crash.

2. Clear up the mess with the file manager mode --- we only need two modes: RESTRICTED and UNRESTRICTED. When we need more we'll add them. No need to pollute code with future "what if"s.

3. Setting file manager mode function has no place in unireader (it was formerly needed because the event notifications was dependent on it --- not anymore).

4. Bugfix: show the correct number of books in UNRESTRICTED file manager
mode when pressing fiveway Right key on a directory.
