CmdUI handling for Developer IDs

For the range of command IDs between ID_FIRST_DEVELOPER_ID and ID_LAST_DEVELOPER_ID, the default SilverScreen behavior is to enable them automatically.

If you desire a different behavior, then handle the WM_CMDUI_ENABLE (0x402) message in your subclassed window procedure. The wParam parameter is the command ID, and the lParam parameter is the address of a CCmdUi object. The CCmdUi object may then be used to call Enable, or SetCheck, or whatever. This is more fully described in the topic A Note on Command IDs
