Upgraded Joda-time Plugin Dependency from 1.3.1 to 1.5 to support grails...

... version > 2.4.x.
For actual version you need to see release notes, since the upgrade notes are outdated for plugin version.

Hence tomcat & hibernate version is not correct. Also upgrading a grails version can not downgrade tomcat & hibernate version.

Well this does not matter since this will be overridden in the parent app.
