Python 3: except exception, e -> except as e (#9698)
* IAccessible object: except COMError, e -> COMError as e.
In Python 2, the exception statement of the form 'except exception, e' was acceptable, no longer the case in Python 3 (requires 'except exception as e'). Thus use the latter in IAccessible objects and others.
* Adobe Flash object: except COMError, e -> COMError as e.
* Log viewer: except (IOError, OSError), e -> (IOError, OSError) as e.
* Input core: except (configobj.ConfigObjError,UnicodeDecodeError), e -> (configobj.ConfigObjError,UnicodeDecodeError) as e.
* NVDA slave: except exception, e -> exception as e.
* NVWave: except WindowsError, e -> WindowsError as e.
