Add ability to associate CFAPI projects to a story

[grodeska]

Previous comments from James Tyack:

If we're associating projects 'from cfapi' is this associating a project stub with a cfapi project?

If we're calling CFAPI, we may need some back-end proxy...I'm thinking that Express may be useful here? I know that there can be issues if you try to call a third party site from client's browser (CORS etc)
