[Building Sakai] Custom POST Entity Broker

[Aaron Zeckoski]

In general, you probably don't want to attempt to use batch processing
with POST. Especially when sending a file since you can really only
send one in your request anyway. You should just post directly to the
endpoint:
POST http://elearn-dev.wits.ac.za/direct/addsiteresource/site/OCCT1000_2012
