I'm still kinda "eh" about whether we should simply smooth over errors where the user isn't giving us something JSON serializable? Isn't an error better in this case instead of polluting their logs cluster with object reprs?

[basepi]

@sethmlarson Obviously at least one person has run into this, and expects us to not fail but rather deal with the object. Doing it this way allows a user to add the __structlog__() method to give it a good log representation. The __repr__() backup will make it pretty obvious what's going on as well IMO.

Just waiting on #46 which will turn these tests green.

functools.partial change looks good to me!
