PropertiesHandle (common-ui 0.0.9 API)

```
public interface PropertiesHandle
```
Interface with convenience functions for handling properties. Instances if classes implementing this interface can be obtained from the PropertiesHandles class.

The methods in this interface come in two flavors, and obey the following contracts:
- read/write:
  The read methods will directly read the value from the properties. If the value is not contained in the properties, then the method returns null. If the value can not be parsed, then a warning is printed, and the method returns null.
  The write methods will directly write the value to the properties. If the value is null, then nothing will be done. Otherwise, properties file will be updated immediately.
- save/restore:
  The save method will obtain the value from a supplier, and pass it to the corresponding write method. So if the returned value is not null, then the properties file will be updated immediately.
  The restore method will obtain the value from the properties using the corresponding read method, and if the returned value is not null, it will be passed to a consumer.
