This commit updates the build to add an `Automatic-Module-Name` entry
to the manifest of each published jar. The names follow a convention
where the hyphen is replaced by a dot:
* `spring-xml`: `spring.xml`
* `spring-ws-core`: `spring.ws.core`
* `spring-ws-security`: `spring.ws.security`
* `spring-ws-support`: `spring.ws.support`
* `spring-ws-test`: `spring.ws.test`
Closes gh-1208
