Improve dependency management for spring-test

In Spring 3.1 the spring-test Maven artifact did not have a required
dependency on spring-core, but there is practically no part of
spring-test that can be used without spring-core. Most test utilities
that are intended to be stand-alone utilities in fact use utility
classes from spring-core (e.g., ReflectionTestUtils). Even some of the
web mocks/stubs use spring-core (e.g., DelegatingServletInputStream).

In addition, the current Gradle build configuration for the spring-test
module is very simplistic -- in that it does not explicitly list any
optional dependencies such as the Servlet and Portlet APIs -- and it
defines a 'compile' dependency on spring-webmvc-portlet.

The resulting Maven dependencies in the generated POM are therefore not
what a typical consumer of the spring-test artifact would reasonably
expect.

To address these issues, the Gradle build configuration for the
spring-test module now explicitly defines the following 'compile'
dependencies:

 - spring-core
 - spring-webmvc, optional
 - spring-webmvc-portlet, optional
 - junit, optional
 - testng, optional
 - servlet-api, optional
 - jsp-api, optional
 - portlet-api, optional
 - activation, provided

The only required dependency is now spring-core; all other dependencies
are 'optional'.
