Updates to allow getActionsForPipelines to be used as a TreeGrid so…

…urce

- Updated the url for the TreeGrid to point at `/etl/pipelines/actions`
- Upated the `getActionsforPipelines` method chain so that it produces output
  suitable for use in an ExtJS TreeGrid.
  - The change @ ubccr#201 was needed due to `get_object_vars` returning a keyed
    array `<property> => <value>`.
  - ubccr#289: This function preps the output for use use in an EXtJS TreeGrid.
  - ubccr#453: This was simplify / declutter the display of the action name from it's
    fully qualified form `xdmod.pipeline.action` to `action` as the nodes
    immediately preceeding the action node will already be displaying the full
    pipeline name.
