Make builder.buildApp overridable

[jamesopstad]

Fixes #000.

Make it possible to override builder.buildApp in the user config or prior plugins. As well as allowing users to provide their own buildApp function, this also makes framework integrations less dependent on plugin order.

I haven't added a specific playground to test this as it is likely the buildApp API might change soon.

It would be great to have a test that proves this works.

I note that you have ticked the box saying "tests included" but that is not accurate, right?
