Title: Fds should be closed

This pull request includes:

* some cleanup of core objects (improved encapsulation of internal state between them)
* adding OrderedDict to tron.utils.dict
* adding FileHandleManager for managing open file handles in action runs. This should ensure that all file handles are properly closed and that tron does not keep them open if nothing is writing to them.
