Author: ate
Date: Sun Mar 30 19:20:03 2014
New Revision: 1583190

URL: http://svn.apache.org/r1583190
Log:
SCXML-99: Add support for the read-only system variables, see: http://www.w3.org/TR/2014/CR-scxml-20140313/#SystemVariables
- implemented with a new SCXMLSystemContext, wrapping normal Context and protecting selected variables
- introducing the required _sessionid and _name variables, and dropping the outdated and no longer needed _eventdata and _eventdatamap variables
- implementing the required _event.type == 'internal' for internal events
