Updated git submodules

Project: so master 8d496b4f1516d25e39bbd909cb7185e74a453cc6

Updated xml tags and moved sleep to bpmn

Per issue, changed "_" to "-".  Also related to a comment to SO-303,
made "sleep" time a property and moved the sleep calls from groovy
scripts to bpmn.
Fixed a few test resources that still had "_" instead of "-".  Changed
variable name from sdnReplDelay to sdncReplDelay.
