Fix for 4 colour decks
Due to an infamous Inkscape bug the following two 4-color decks, Slavic Costumes and Rheinland had leftovers from the original black-red scheme stored. Now for librsvg and AisleRiot this isn't a problem and everything looked as expected but Qt with its lacking SVG engine picks up those leftovers and still shows the original colours.
So this is basically just to ensure compatibility to e.g. KPat.
I also fixed positioning issues for the standard Neoclassical.
For Slavic Costumes I also fixed slight positioning errors.
For Rheinland I also increased the size of the suit symbols on the court cards.
