[Lucas][UI] Enabled iisidecontroller in viewdeckcontroller and fixed bug of not displaying on the first place; Fixed bug of navigation bar not covering readerviewcontroller.

1. By removing viewdeckcontroller as the rootviewcontroller and call it after tapping the tableviews. Initialize all the systemitems and handlers at the same time.

2. After pushing controller to the front instead of the previous readerviewcontroller, the navigation bar worked fine.

Checkin Classification: New features; Bugs fixed.
