[Glade] Created branch glade-3-12

[Juan Pablo Ugarte <juanpablougarte gmail com>]

Hi guys, I just created a Glade stable branch for GNOME 3.4 named
glade-3-12

BTW would not be nice to include a script we could run to create a git
symbolic reference with the corresponding gnome branch name in this case
gnome-3-4

Perhaps it is already possible to run something like
# git symbolic-ref gnome-3-4 glade-3-12
But i am not sure if everything would work out of the box.

any ideas?
