android-native: auto hunt, in-client account registration, mobile UI polish

- Auto hunt (client-only): PythonPlayerAutoHunt.cpp + AutoHuntScript.inc as the
  embedded mt_autohunt module, AUTO touch button, F9/F8.
- Account registration: tools/40250/register_server.py (rc.d mt_register, :11080)
  inserts into account.account; net.RegisterAccount/GetRegisterAccountResult
  (PythonAccountRegister.cpp) and the mt_register login-window dialog
  (RegisterScript.inc).
- --py-exec also runs in --login-screen mode for scripted login-screen tests.
- Touch controller, window manager and render command updates for the
  Android native client.
