Completed integration of apConfigure()

The 'A' command now resets any existing WiFi functionality so that it can start an Access Point without needing to first reboot.

To Do:  Add a method to cancel out of apConfigure() and reboot by pressing control button.

To Do:  Create time-out for commandMode()
