move requel project package to new module

[rreganjr]

branch 1.0.3

I created a new command module and requel module and moved all the root level code under the requel module. I had to move classes ExceptionMappingCommandHandler, RetryOnLockFailuresCommandHandler, and DefaultCommandHandler out of the command module because they had dependencies on the repository/persistence code.

I also switched logging from explicitly referencing log4j to using apache commons logging.

the app builds and runs.
