hgweb: make hgwebdir handle dict/list paths the same as config paths

Before this patch, the only way to get hgwebdir to honor the recursive paths
was to create a config object or a config file with the recursive paths in it.
This patch makes hgwebdir treat paths the same whether passed in as a list,
tuple, config or however hgwebdir supports passing paths.
