3.5 development opens

Hi,

with the 3.4 release out (and it was a really smooth release, thanks
everybody), the hard code freeze is now lifted. Now is a good time to
make 3.5 plans, write feature pages if you have interesting features
that you want to work on, and dive into new development. But please
create gnome-3.4 branches first, to keep strings and UI stable for
3.4.1.
