Downstream webpack will need any dependencies src/ depends on so it can
successfully build. Also if multiple packages being built into a larger
script share a common dependency version range, they can share the
dependency instead of duplicating it. This will save built file size,
execution time, and memory.
Add dependency on babel-cli and the intl plugins for extracting strings from source.
Include script for combining extracted strings into a single source chrome-i18n file as a binary from this package.
Breaking change - bumped major version to 2.
Restructured to support multiple components. Package default is just localeData for currently supported locales including the name for each language.
messages for each component are exported as separate files in locales. Clients of l10n will need to import messages for each of the compents used and combine them.
