Alpha 7 - at long last!

One of our more delayed releases due to all the activity with Google Code-In over winter, then followed immediately by getting into Google Summer of Code again! Yay?

Some 322 engine commits, 103 closed engine issues, plus an untold amount of module changes. Maybe some change notes soon, but so much to try to cover! With a little luck we can get back to smaller releases and do Alpha 8 within a month.
