Print the message of the day

This uses the Nerves.Runtime library. In the unlikely event that it's not available, it assumes the system isn't ready and doesn't print the MOTD.

Options:

:logo - a custom logo to display instead of the default Nerves logo. Pass an empty logo ("") to remove it completely.
:extra_rows - custom rows that append to the end of the MOTD.
