patterns: direct use of `store`

* INCOMPATIBLE Drops `setVar()`, `getVar()`, `delVar()` and exposes the
  `engine.store` dictionary directly, with an added `setget()` method
  that acts as `getVar()`.

* INCOMPATIBLE Renames s/getCurrObjId/curr_obj_id/ and
  s/getCurrTaskId/curr_task_id/ which are now properties. Also renames
  s/getObjects/get_object/ which now no longer returns index.

engine: unused PhoenixWorkflowEngine

* INCOMPATIBLE Removes PhoenixWorkflowEngine. To use its functionality,
  the new engine model's extensibility can be used.
