Changeset 23 for trunk/fmgVen/lib/ven

Refs #3 - Spring 2.5 libraries are added. Old spring 2 jar is removed. The main dependency is spring-jdbc.jar and spring-beans.jar, spring-core.jar and spring-tx.jar are referenced from them. For testing with postgresql, its driver is added.

The interface is translated to the new Ven class. Instead of adding 'object' to all of the methods, I aimed to make it less verbose, so just shortened the name of the methods to list, get save, delete.

Lastly, we have a class to demonstrate the usage called 'Sample' in the test packages.
