Title: Include current environment variables for child processess

When using this module in Mac/Windows with a node app that spawns child processes, those processes lose all their environment variables unless passed explicitly.
Extending over `NODE_ENV` also ensures the proper value in case a user has it defined as a system-wide environment variable.
