ebulk new release (1.1.7)

Fixes and new features:

• Getting data stream lists from datasets in Ebulk is done in batches of files (#1000 by default) to avoid expensive queries in wendelin for big datasets (thousands of files). Batch size can be set by a new command argument in ebulk tool.
• Ebulk handles new wendelin scripts to get count of streams per datasets and data stream list
• "info" command
• Fix reference/path issue
