THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

- `IDataProvider` was converted to using `long` instead of `int` to better line up with JPA and other persistence frameworks. This has caused a rather large cascade of `int` to `long` changes all over the repeater packages (WICKET-1175).
- All classes in wicket-extensions which are related to repeaters with sorting behavior have improved generics
related to the sorting property (WICKET-4535). In most cases you just have to add ', String' to the previous parameterized type. For example: IColumn<Entity> becomes IColumn<Entity, String>. But now it is possible to use other type for the sort property than java.lang.String too.
