Alabaster Dawn Android port v0.5

v0.5

• Exiting the game works. The title screen's Exit and System.quit were shim no-ops, so the
  engine hid its own menu and waited for a process exit that never came — the frozen picture that
  ends issue #1. Both now leave the app.
• Exit ends the app process, so the next launch is a fresh process with a fresh WebView renderer.
  The old "swipe it out of recents first or the second start comes up black" workaround is gone.
• The side menu (Back) is now one uniform, full-width, icon-led list — the whole row is the tap
  target, and the current picture position is a filled pill.
• The port's version is on the setup screen and in the side menu's status block.
• The record names the game's build too, not just the port's: game 0.1.0-10 Early Access.
