also: - added `date_time` converting constructors from `date` and `time` - added `is_key<>` and is_key_or_convertible<>` metafunctions - exposed `TOML_NAMESPACE_START` and `TOML_NAMESPACE_END` macros to help with ADL specialization scenarios - added encoder and decoder for `toml-test` (closes #125)
