Change the way schemas are handled

[Akramhar]

Instead of bundling the schemas in the app it would be nice to pull them from the github repo here and then copying them in the working folder in the same way we are doing now. It would be similar to what has been done for the component (see here)
This would remove the need to update the schemas in multiple locations.
