Option to disable unfocused fade?

[mnpenner]

I really like this theme, but I don't like how it fades out the split panes that aren't focused. I understand the benefit of being able to clearly see which pane you're working in, but I run loggers in 3 out of 4 panes, and I want to be able to see them clearly.

Is there any way to disable the unfocused fade?

Pull request welcome for an option :)
