Changes
- Use yargs to document existing options: `pretty`, `sync-fbsource`,
`sync-www`, `unsafe-partial`.
- Move `_` arg to `names` option for consistency with other options and
discoverability through yargs help
- Add `bundle` option in place of `argv.type` that allows choices of any
BundleType to be passed in directly.
