Lancelot reference designs for Stratix 1s40

Open the 1s10 design in Quartus, go to Assign -> Device, and select the 1S40 (be specific about the package type/pin count'/speed grade). When prompted if you want to remove location assignments select NO. Then re-compile in Quartus.

Background: The 1s10, 1s10ES, and 1s40 Nios development boards all have the exact same pinouts, the only thing that needs to be changed is the device assignment. This is *not* true of the 1C20 board so be careful!
