Updates

A few small updates:

• Almost there with 'Hello, World' in SystemC - the whole tree builds, just finishing up fixing some link-time errors.

• There is something wrong with SF.net's Subversion support, which many people have been complaining about for over a year now. I couldn't check in or out, so I have moved the repository over to Git, which I don't prefer but do know how to use, and everything appears to be working smoothly now.

More updates soon....
