Subject: [PATCH] Fix navigation drawer not switching screens on first launch

introduction_view was a second content child of DrawerLayout (no
layout_gravity). Showing then hiding it on first launch broke
DrawerLayout touch handling, so taps on menu rows closed the drawer
instead of selecting the item, and onNavigationItemSelected never fired.

Wrap the content and the intro overlay in a single FrameLayout so
DrawerLayout has exactly one content child plus the NavigationView
drawer. Layout-only change.

Fixes #373
