Added wallpaper scaling
Added support for wallpaper scaling.
The configuration window has not been modified, so the user has to manually edit the .colorscheme file to change the filling strategy (FillStyle).
0 corresponds to tiling, which is what Konsole currently uses.
1, 2, 3 are Stretch, Center and Adapt, respectively.
Edit: added screenshots
