json_reformat.py example uses parse_complete instead of complete_parse

[troyjfarrell]

In the json_reformat.py example, the ContentHandler defines the parse_complete method: https://github.com/pykler/yajl-py/blob/ba54a7dac608eb5da5d6f7c4d59f2274e8cacde4/examples/json_reformat.py#L35-L36

In yajl_parse.py, it appears that the method should be complete_parse: https://github.com/pykler/yajl-py/blob/ba54a7dac608eb5da5d6f7c4d59f2274e8cacde4/yajl/yajl_parse.py#L125-L126
