Lots of small changes as a result of this
other minor clean up
Tests should pass now.
And if \Themes\vs2015light.vstheme can't ben loaded, we should be OK now...
- Clear redundant settings form app.config
- Deleted DesignModeTest as ThemeManager can now be used in design time without adjustements, removed usage from all custo elements
- Instance _themeManager in NGNumericUpDown at object creation to avoid null reference errors
- Errorsform instancing is now defaulted to DockBottomAutoHide in frmMain
-Fix missing panel at startup by adding a blank panel, temporary solution as magic library is beign phased out
