    Changing publishing mechanism to allow referencing context variables

    * All previously published variables can be now access using '$.'
      as in other places. E.g., if we had variable 'var1' in the context
      we can use '$.var1' to access it in 'publish'.
    * Action/workflow result can be referenced using "$.taskName.".
      E.g, if task name is 'task0' and its action/workflow returned {x: y}
      then 'x' can be referenced using '$.task0.x' in 'publish'.
    * Fixed a lot of unit tests
    * Fixed with-items implementation (part related to task output)
