- moves some code in ThemeNew.cpp (calcGradient and calcAlpha to the bottom)
- added possibility to use a shading effect on inactive dialogs (luminance and dim are builtin, and special ablility to specifiy a own expression, evaluated via the evaluator)
- adds also a color cache (atm it's generated on startup)
- uses luminance effect by default
- bumps theme config version to 7
