Update node_list for 4.7

Thanks... Once my latest (4.6) updates to pathauto have had a little time to propagate and prove their stability, I'll cut over to developing for 4.7...

  $displaytype = node_invoke($type, 'node_name');

does not give any result.

I mean, in the current CVS, of course!

Updated patch for current HEAD. I tested the patch, it works as expected.

Initial port of pathauto to 4.7 committed, including the call to node_get_types(), thanks!
