I692 jts geometry

## Changes
* Added JTS Geometries support.
  * Now `querydsl-spatial` can be used with `hibernate-spatial` version **4.3**.

## Configuration

## Example

Entity
```java
...

import com.vividsolutions.jts.geom.Geometry;

...

@Entity
public class Entity {

	...

	// The @Type annotation is Hibernate specific, and the only non-JPA annotation that is required.
	@Type(type = "org.hibernate.spatial.GeometryType")
	private Geometry geometry;

	...

}
```
`Predicate` for use with Spring's `QueryDslPredicateExecutor`
```java
...
public static Predicate spatialWithin(Geometry geometry) {
	return QEntity.entity.geometry.within(geometry);
}
...
```
These can be combined, since querydsl-spatial depends on both geolatte and jts.
