Initial commit of de10-nano recipes

Please note that this is purely for development.  Only superficial
efforts have been made to resolve security concerns, and it should
be noted that the board ships with an EMPTY ROOT PASSWORD and support
for root login via ssh.  This allows passwordless access to the board
via ssh.
