Setup

I'm submitting this as a PRQ now as it (shouldn't) make breaking changes to production, however does mean that development can be done without access to the production environment.

Even more than usual, I recommend testing these changes in one of the test directories first before putting it live to the general populace (or potentially even waiting off until after the end of term)
I was thinking about https://github.com/UniversityRadioYork/MyRadio/blob/setup/schema/data-submenuitems.json

But then I realise what you meant... Of course we already have the bloody files :P
