Closes #121 - Combined properties classes into FluoConfiguration

Pull request for #121

Fluo Configuration extends Apache Commons Configuration. Created unit test and updated
implementation to use new configuration class.  Added methods to verify
if configuration is set properly for client, admin, worker & oracle.
Its nice having this file with all the props.  Should probably comment out a lot of the props in the file.   If thats not done, then user will use this file and whatever is in here will become the defaults instead of the defaults in the code.
