a newer version

I had some new boards for Quad303 in which I have added :

1. some mounting holes for new system builders.
2. Traces modified to take MJL's PNP+NPN. If you find appropiate
output pairs, you can snug them in and give a try. They can be
soldered onto the board directly (ideal for new system builders)
3. Some components relocate to spread better among available
space
