Subject: [PATCH] A bugfix for Foundry regarding the with-colorset
 functionality. If set on an element which is used on the welcome page (for
 category is selected) the get-colorset function did cause an error because it
 returned an empty sequence which is not allowed. Now get-colorset will return
 colorset-0 for the root category.
