Experimenting with some new ways to handle config

For now I’ve chucked it on Flarum\Core as a static method, but
ultimately I think we will need a ConfigRepository abstraction (whether
it replaces or sits underneath the Flarum\Core static method I’m not
sure).

Also starting to think about multisite scenarios, I think this is
important. The Forum model could actually end up with a database table
behind it, and each forum would have its own config settings? Haven’t
really thought about it too hard yet…
