website - fix some font-warnings in style.css
|Reported by:||SF/clemty||Owned by:||fingolfin|
although the css passes the w3 check there are still a lot of warnings when you follow the validator link;
this patch to style.css aims to fix the following warnings (each occurs 2-3 times):
"Family names containing whitespace should be quoted" "You are encouraged to offer a generic family as a last alternative"
I hope the changes don't affect display/compatibility, and while these changes are not necessary it seems more standard-conform this way
