[PATCH 4/7] refs: separate decoration type from default filter

[Andy Koppe <andy.koppe@gmail.com>]

Add 'include' bit to struct ref_namespace_info to determine whether a
ref namespace is to be included in the default decoration filters,
instead of using the decoration type for the purpose.

This is to allow adding ref namespaces that do have a decoration type
but that are not shown by default.
