Added Files:
Implemented a rudimentary log manager to manage the current logs for each
system. Also implemented a listener framework to notify clients of log model
events (currently only log done, to make writing to an XML file possible)
src/java/de/fhworms/ztt/cpr400/logmanager/LogDoneListener.java
src/java/de/fhworms/ztt/cpr400/logmanager/LogManager.java
