API no longer fails auth on signature timestamp variance.
Fixed send_email issue.   Consolidated If, Loop and While evaluation.  Added a "datetime" comparison option with format.
Fixed the "click to add another" links on task edit so they're not as easy to accidentally click.
Task Engine - added a global variable to access the result summary.
Exists command now has a "has_data" option.
