Stable Release - `.env` file support

Full Changelog: v0.1.2...v0.1.3-pre

• Add the posiblity of using .env files in case of encountering in a dev environment.
• .env files will not work in production unless there's a existing .env file in the current directory, in that case, it will use what is defined in that file.
