Currently, LinkSuggest uses $wgContentNamespaces for the list of namespaces to suggest pages from. Normally this is fine, but on Yugipedia this means that pages from various ancillary custom namespaces get suggested as well, which should rarely actually be linked to. Removing these namespaces from $wgContentNamespaces isn't appropriate for us, though, since we want them to be accessible from Special:Random, to count towards the {{NUMBEROFARTICLES}} count, etc.

Therefore we'd like if a configuration variable could be added to allow overriding $wgContentNamespaces for the purpose of listing the namespaces this extension should suggest pages from (allowing it to default to $wgContentNamespaces, to preserve the current behavior, is fine).
