From Ted Ross, https://issues.apache.org/jira/browse/QPID-782

The attached patch makes the following changes:

The --load-dir option has been renamed to --module-dir
The --no-modules option and been replaced by the --no-module-dir option. This new option suppresses ONLY the loading of modules from the directory.
The --no-data-dir option has been added to suppress the use of a data directory.
Logging has been added for data directory lock and unlock.
