AppVersionUpgrade

```
public class AppVersionUpgrade
extends java.lang.Object
```
TODO for now just shuffles directories during startup. Could be extended to do other tasks, delegate control to components/plugins to upgrade, only run upgrade once when a version change is detected. Would need to solve issues with timing of upgrade wrt to component initialization e.g. migrate existing directories prior to init of default dirs/data by the components
