extend ClearSkinString() range

atm when switching between skins some strange localization issues can occur where labels from the previous skin can take over labels of the skin which got loaded.
i looked through some skins and checked in which  skin id range they are using.
xperience and nox go up to 45xxx  so i took 46000 as the upper range limit.

if this has any downside i´d also happily adjust the labels inside the skin to use only 31xxx. this would be the quicker way though^^
