Added Milestone repository to aspects module to find AspectJ 1.6.11.M2. Reduced logging dependencies to test scope, altered two classes to use SLF4J instead of Commons logging. Use Log4J 1.2.16 as this does not require explicit excludes for mail, JMS and JMX anymore.
Extracted common functionality from project Hades to build a common infrastructure for generic repository implementations independent of the underlying persistence mechanism. Fixes DATACMNS-2, DATACMNS-3, DATACMNS-4, DATACMNS-5, DATACMNS-6, DATACMNS-8, DATACMNS-9.
