Switch accepted arguments for parser methods to args and kwargs

[djhoese]

It is probably more pythonic to accept *args and **kwargs for positional and keyword arguments. The parser methods/functions accept a single keyvals which is meant to be a dictionary. I'd like to change them to accept args and kwargs instead. Backwards compatibility could be maintained with an isinstance. This signature would also match the stdlibs format functions. Methods affected would be compose and globify.
