+Subject: [PATCH] register now checks for missing ctypes
+
+If ctypes is None, then no input hooks may be registered; `InputHookManager.register` skips registration of input hook classes. Also updated `__init__` to no longer skip creating the instance attributes, to prevent AttributeError exceptions at load time.
