Further standardize and preconfigure default and required dependencies for Hippo based projects

Standard and assumed provided dependencies for all Hippo projects extending from hippo-cms7-project:

• geronimo-jta_1.1_spec-1.1.jar
• jcr-2.0.jar
• jdo2-api-2.3-eb.jar
• mail-2.4.3.jar

As predefined container-wide dependencies, these will be pre-configured for cargo to the deployed to tomcat common/lib.
Furthermore, in the website-archetype and gogreen assembly distribution.xml these predefined dependencies are not packaged anymore in a distribution
as they are presumed (required) to be provided by the container itself (on the common/lib classpath).
The Hippo and application specific shared dependencies, like hippo-repository-api, hst-api, hst-common, workflow common etc. is what remains to be deployed to shared/lib and therefore packaged
with every release.

Tasks:

• update cms7-project-pom for the above
• update website archetype for the above
• update gogreen and hst demosuite and possible other example or test projects for the above
• remove activation and mail dependency definitions from all cms7-project-pom extending projects

Note: none of the above should have any technical impact, its merely further standardization and cleanup of redundant project configurations.
