    Ensure dict orders are deterministic

    Python 3 enables hash randomization by default, additionally tox 1.7
    turns on the same randomization for earlier versions of python by
    default. Need to ensure that order of iteration over the yaml data and
    resulting XML has deterministic order for testing.

    Adapts https://gist.github.com/enaeseth/844388 which ensures data read
    by yaml will have its order retained in a predictable manner across
    multiple python versions.

    Additionally it seems more sensible to ensure that the order of
    generated XML snippets corresponding to the input yaml files are
    consistently in the same order as the entries in the source files.
