v1.2.16: ATRACT, No FN, Server hang
Fixes a few things:
- Added a VBI that sets ATRACT (0x4D) to 0. Disables the screen saver color rotation.
- Added some more checks to the get_settings code that, if sio_openkey returns 0, we just set defaults. This can happen if there is no FN or (I'm assuming) the FN has no SD card.
- The server did not have a timeout set for the request call. This could cause the server to hang, waiting for a response from the URL. Timeout is now 30 but probably could make it shorter.
