Adding Access-Control-Allow-Origin for angular2

[jamesmorgan]

These are the changes I need for each endpoint so I can access them from angular 2 admin app.

[andygray]

can probably add this across the board somehow

[jamesmorgan]

ye very true, add a a piece of middleware like this to app.js before the other routes are defined:

app.get('/*',function(req,res,next){
    res.header("Access-Control-Allow-Origin", "http://localhost:3000");
    next(); 
});
