Broken links for constants and functions in global namespace

[toxalot]

Each structural element links to a specific page. If it's a class, the link points to classes/ClassName.html. If it's a function in a namespace, the link points to namespaces/namespacename.html#function_function_name.

However, if the function is in the global namespace, the link points to namespaces/.html#function_function_name. And for contants, the link points to namespaces/.html#constant_CONSTANT_NAME.

I imagine anything in the global namespace should point to namespaces/defaul.html#whatever
