Coala Online is broken due to CORS

[joeytwiddle]

https://coala.io/#/coalaonline does not work due to the SOP security restrictions in browsers. This is bad for Coala marketing and therefore adoption!

# Chrome console:
Failed to load https://api.gitmate.io/coala_online/: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://coala.io' is therefore not allowed access. The response had HTTP status code 504.

# Firefox console:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.gitmate.io/coala_online/. (Reason: CORS header 'Access-Control-Allow-Origin' missing).

We can use CORS to get past these restrictions. (MDN, Wikipedia)

To do that, we must add some HTTP headers to the response provided from api.gitmate.io

Where is the code for that API server?

Oops, I posted on the wrong repo.

I have moved the issue to coala/landing-frontend#282
