    Fix compatibility problem with Katawa Shoujo 1.3.1
    
    The game fails to start with renpy-6.99.12.4:
    
    I'm sorry, but an uncaught exception occurred.
    
    While running game code:
      File "game/ui_settings.rpy", line 21, in <module>
      File "renpy/common/00compat.rpy", line 134, in _set_script_version
        config.window_auto_hide.remove("call screen")
    ValueError: list.remove(x): x not in list
    
    -- Full Traceback ------------------------------------------------------------
    
    Full traceback:
      File "/home/rondo/ui_settings.rpyc", line 2, in script
      File "/usr/lib64/python2.7/site-packages/renpy699/renpy/ast.py", line 814, in execute
        renpy.python.py_exec_bytecode(self.code.bytecode, self.hide, store=self.store)
      File "/usr/lib64/python2.7/site-packages/renpy699/renpy/python.py", line 1695, in py_exec_bytecode
        exec bytecode in globals, locals
      File "game/ui_settings.rpy", line 21, in <module>
      File "/usr/lib64/python2.7/site-packages/renpy699/renpy/defaultstore.py", line 92, in __setattr__
        renpy.store._set_script_version(value)  # E1101 @UndefinedVariable
      File "renpy/common/00compat.rpy", line 134, in _set_script_version
        config.window_auto_hide.remove("call screen")
      File "/usr/lib64/python2.7/site-packages/renpy699/renpy/python.py", line 610, in do_mutation
        return method(self, *args, **kwargs)
    ValueError: list.remove(x): x not in list
    
    This happens because "call screen" element is being unconditionally
    removed from config.window_auto_hide list, though it is not always
    present there. A simple if check fixes this.
