Added error handling during dotenv loading
Some issue people report are because of misconfiguration or bad .env files. To mittigate this i added error handling for this. - Panic/Quit on a LineParse error, which indicates bad .env file format. - Emits a info message when there is no .env file found. - Emits a warning message when there is a .env file, but not no permissions. - Emits a warning on every other message not specifically catched.
