Feature/seqware 1400 oozie improvements

This was work done to improve the Oozie workflow engine.  Some highlights include:

1) upgrading deps to cloudera 2.0.0-cdh4.1.2
2) ensuring the maxMemory requirement is passed correctly to oozie
3) ensured the ${workflow_bundle_dir} variable is properly replaced in the ini config file before running a workflow (this is not robustly done, we need to make sure all engines handle magic variables consistently still)

I tested using the Java HelloWorld workflow created from the maven archetype.

As a bonus I also found the bulk S3 uploader plugin code I wrote a while back but didn't check in.  I'm checking this in here for safe keeping.
