Improve instances.json file (#39) [skip ci]

In this pull request I made few modifications to instances.json file to make it more friendly to any scripts that will be using it as a source of instances in future:

* I added protocol to all URLs. Most scripts expect URLs to already have protocol and lack of it may cause minor issues.
* I turned instances.json from array of strings into array of objects. It makes the list more organized and it would be easier to add or remove instances in future.
