I should have done this before but anyway, if you do not agree I'll remove whatever was already contributed

I think I'll release T4 as GPL or LGPL, but I could change my mind until release and say MIT or whatever, anyway this will obviously be opensource.
But in order to avoid the headaches og T3 and GPL-isation, I'll ask people that contribute to release copyright to me, or to give me right to relicense the code as I see fit (you can add a "as long as its opensource" if you wish, it'll never change

Thanks!
