Inline Environment Variables Webpack Plugin

A webpack plugin that replaces all instances of `process.env.***` with actual environment variable values at build time. Current stable version is 1.2.1, with infrequent releases. Key features: inline all environment variables by default, select specific variables using string/object/array config, or define static values. No runtime dependencies. Simpler alternative to webpack's DefinePlugin for basic env inlining, but limited to environment variables only and primarily intended for development/debugging use cases. Last updated in 2017.
