Updated Time Line for TestGL

Woops, I meant to send this a few days back.
Loften, Patrick and I stayed a bit after the last telcon last Monday and
came up with an updated schedule for TestGL.

1 - WG version tomorrow;
2 - 2nd PWD asap after than (may 2nd);
3 - (First) Last Call (2ndPWD + 3 months, i.e., soon after Crete).

Peter.
