RFR: 8380: Support dark mode in graphs [v2]

[Marcus Hirt]

> Also added dark mode support in the Automated Analysis page, and fixed wrong version in a few properties files along the way. 
> 
> Added a simple debug console for the next person needing to do something in the Automated Analysis page. I can't wait for the IE based WebView used by default by the SWT Browser component on Windows to die a well deserved death...
