Update Timezone to 0.0.16.

Update Timezone from 0.0.14 to 0.0.16.

Timezone 0.0.16 has been updated to include the `tzdata2012j` version of the IANA timezone database, plus support for many more locales was added in Timezone 0.0.15.

You should still use a specific version of Timezone in your `package.json`. A stable `0.2.0` release is pending. It will allow for a `~0.2` version pattern.
