Removing deprecated ClosedRepairOrderLookup that is being removed in favor of
GetClosedRepairOrderRequest.
Implemented method to get repair order detail.
Re-factored IRequest to include required info in ctor.
Added zip of XML from test Open Repair Order Lookup call.
Might as well add check for servername too.
Refactored IRequest to remove empty elements from the XML request since
it appears as if the OpenTrack system chokes on them.
Implemented parts inventory request.
Meh, don't really need a sample XML of the request for open ros.
Rough implementation of AddRepairOrder request, little to no error handling.
