The workers where co-dependent anyways as the non-asset worker
was started after the games worker had sent back its results.
By combining them we can move any data manipulations to the worker
and simplify the handling in RareCore.
This is the last change of the `backend_refactor` branch. This makes
`RareCore` the centerpiece of Rare by moving initialization before the UI
is brought up. RareCore is now in control of creating and querying `RareGame`
objects, re-introducing the ability (incomplete) to refresh the games library.
As a result, ApiResults has been removed.
