University Program IP Cores and Quartus II 7.2

This is not a bug. The DE External Interface core no longer creates the extra clock, since the VGA core no longer requires it. There was an issue with the VGA core while passing data from the 50MHz clock domain to the 25MHz clock domain. Now the VGA core only using the 50MHz clock domain, but a 25MHz clock is still needed to be sent to the VGA chip via the VGA_CLK pin.
