UrlEncoder (Wicket Util 9.13.0 API)

java.lang.Object
- org.apache.wicket.util.encoding.UrlEncoder

```
public class UrlEncoder
extends Object
```
Adapted from Spring Framework's UriUtils class, but defines instances for query string encoding versus URL path component encoding.
The difference is important because a space is encoded as a + in a query string, but this is a valid value in a path component (and is therefore not decode back to a space).
