dotenv for c

This small package adds support for loading .env files. Just call the env_load function with a valid path, that contains a file named .env, or the path of the env file itself. If can't be loaded, it'll return -1, 0 otherwise. If the second parameter is set to true, already existing environment variable will be replaced with the new value.

In the file, comments can be added by starting the line with #. It's also possible to nest the variables, but in that case, the used variables need be already defined.

Quotes won't be removed from the strings.
