Text pane colors in Browsers in VA8

[koschate]

With the advent of tabbed browsers in VA8, we found that there were default background colors being set in many browser and inspector windows that made it impossible to read the contents of the windows when developing under AIX. I wouldn't be surprised if this were also true in Linux. To get around this problem, I went through the StsTabbedBrowserApp with its subapplications, and removed the explicit setting of background colors, which is probably how they should have been implemented. I'm attaching a differences export from V 8.0.2 of the application for those that are interested.
