Changes made to Logman to make use of log4j

This is only makes Logman use log4j nothing else.


I will be looking into the splitting of files vary soon.
So I guess that this PR can stay open until then.

May need to be push a few new files to the imp repo, the log4j config file will have to be edited, so it will need to be included to be able to over ride the NMS one.
