ros.org page for `urdf_parser_py` is confusing?

[EricCousineau-TRI]

At present, the urdf_parser_py page on ROS.org seems a bit mixed up: http://wiki.ros.org/urdf_parser_py

It refers to the old robot_model_py package, and indicates that it's only supported for EOL packages; it then mentions that its been renamed to urdfdom_py; if you click on that link, it takes you to that page which actually refers to the urdf_parser_py page? http://wiki.ros.org/urdfdom_py

It does seem that robot_model_py does still have its old page: http://wiki.ros.org/robot_model_py

A wee bit confusing...

K, it was rather confusing, but I made the following changes:

• Added redirection in urdf_parser_py, to urdfdom_py: http://wiki.ros.org/urdf_parser_py
• Added the "History" bit in urdfdom_py: http://wiki.ros.org/urdfdom_py#History
• Added redirection in urdf_python: http://wiki.ros.org/urdf_python
• Added redirection in urdf_parser_python: http://wiki.ros.org/urdf_parser_python
• Added transition note in robot_model_py: http://wiki.ros.org/robot_model_py

@clalancette @sloretz Can I ask what other changes y'all might suggest?

Also, it's still kinda confusing that urdfdom_py is what has the documentation for urdf_parser_py. Is it possible to change that at some point?
