added support for log4j overrides - and have QR do the magic for you rather than have to duplicate a whole file
This allows you to have a log4j-overrides.properties file and it will read it and add it over the current log4j configuration.
In JIRA we have no way to do this without copying ALL if the standard config.
This is additive.
Only happens of you have the log4j 1.x in play
