  -----------
  Update Xcode project to fix linker warnings

This fixes several warnings of this type:
ld: warning: direct access in return_to_play_side_exception::execute()
to global weak symbol typeinfo for lua_jailbreak_exception means the
weak symbol cannot be overridden at runtime. This was likely caused by
different translation units being compiled with different visibility
settings.
