GTK+ 3.0 gtk-style-context has landed

GTK+ 3.0 gtk-style-context branch has been merged with master. This is an API change that causes a few modules to break in JHBuild:

• gnome-utils
• nautilus
• Evolution-Data-Server
• gnome-power-manager
• brasero
• empathy
• epiphany
• network-manager-applet

I created a tracker bug so developers can see how other modules adjust to the API change.

GNOME 3.0 isn't buildable... for now...
