AmfController#getway_old

Get an old version of a way, and all constituent nodes.

For undelete (version<0), always uses the most recent version of each node,
even if it's moved.  For revert (version >= 0), uses the node in existence
at the time, generating a new id if it's still visible and has been moved/
retagged.

Returns:
0. success code,
1. id,
2. array of points,
3. hash of tags,
4. version,
5. is this the current, visible version? (boolean)
