BangleApps repo changes (apps.json removal?)

Ok, great! For once we're all in agreement!

I assume there is a good reason (it would be pretty wasteful) for not doing the concatenation of apps.json client-side.

Yes, there's some discussion in those issues, but right now the app loader can start displaying apps after loading ~10 files. Client side it'd end up having to load 300+.

I've changed my apps.json to only show the apps that I've changed on my github, so it's easier to understand, move around, etc.

That's a good point! It'll need documenting, but this is still totally fine. There'll be some 'magic code' inside apps.json, but if you want just the apps you're interested in, you just pull that out and put in the contents of each metadata.json file you care about.
