Global Header Information

I really like how you can have the header area customized for each individual page but I think it would be really nice if you could set a “global” section of the header that would be the same on all template files. That way, you only have to change items that effect all pages once.

It would also be nice to be able to set a global Site Title to be appended to every page. Along with a separator icon or just a blank space.
