Unicode values in Python 2.7

[loganasherjones]

Oh unicode. I love you so much.

Another bug. This time, if you have unicode values in your dictionary, when the dictionary dumps the data out using yaml.dump it shows up like `!!python/unicode config: !!python/unicode value:``

This is not the intended behavior, and should be: config: value

I'm pretty sure we just need to use safe_dump instead of dump.
