Please add parameters to getPagelist

[chang-zhao]

Requesting dw.pagelist(':') gives all the pages, maybe many thousands. Users may be interested in limiting the depth of search:

dw.pagelist(':', {'depth': 1})

but that gives

TypeError: DokuWikiClient.pagelist() takes 2 positional arguments but 3 were given

It's reasonable to add the second parameter here:

    def pagelist(self, namespace):
        """Lists all pages within a given namespace."""
        return self._xmlrpc.dokuwiki.getPagelist(namespace, {})

Kind of

    def pagelist(self, namespace, opts = {'depth': 0, 'hash': False, 'skipacl': False}):
        """Lists all pages within a given namespace."""
        return self._xmlrpc.dokuwiki.getPagelist(namespace, opts)
