DocSortable (ebean-annotation 6.15 API)

```
@Target(FIELD)
@Retention(RUNTIME)
public @interface DocSortable
```
Used to indicate that a particular string property should support sorting. What this typically means is that for ElasticSearch an additional 'raw' field is added that stores the un-analysed value. This un-analysed value can be used for sorting etc and the original field used for text searching.
For example, customer name and product name are good candidates for marking with @DocSortable.
