Split pane tab headings

[savish]

Please change the colours (either the tab, or the tab header text) for the non-focused tabs in a split pane configuration.

Reproduce:

• Open some tabs (at least 2)
• Split windows using Cmd+\
• Select the second pane

The name of the non-focused tab in the first pane will be barely visible due to the colour of the text changing when the pane goes out of focus.

Great theme by the way!

Thanks for the feedback! I'll fix this.
