Delete the "obsolete" package

It's dead weight.
Move "WMT.html" to "index.html"

Now "WMT.html" won't shout at @mcflugen.

Note: for backward compatibility, when deploying on csdms.colorado.edu,

Set up new URL and path for updated "save as" action

The API POST call is `api-dev/models/saveas/<id>`, where <id> is the ID

Set up action for model "save as"

Action still goes through DataTransfer#postModel.

Load saveType member variable

Also:

* Use the correct URL path
* Append "copy" to model name, if needed
* Add some descriptive comments
* Remove obsolete login check
