Random CotD Script Implemented

A couple of our scripting geniuses put together another spiffy thing to look at on the main page. Back when we were working on our CCG project we had Cards of the Day and those have been going to waste for the most part since we got too busy to keep that up. But now we've got them randomly coming up when you reload the main page. At this time we're not planning to add new cards, but maybe we will someday when there's more time.
