logmanoriginal 2460b67886 cache: Refactor cache factory to non-static class
The cache factory can be based on the abstract factory class if it
wasn't static. This allows for higher abstraction and makes future
extensions possible. Also, not all parts of RSS-Bridge need to work
on the same instance of the factory.
