Remove all files that have been separated into a new library 'objectlib'
Lots of changes:
1) new 'info' button (not working yet)2) make all dialogs modal; rework the way the Pattern Dialog appears.
Bigger 'OK' button in Dialogs.
Make it so that the Navigation Bar does not re-appear when we pop up a DialogFragment.
Now there's noly 1 case when it still reappears: it's when we pop up a PopupWindow.
Display the 'Privacy Policy' dialog (only if locale is set to ZH - chinese requirement)
