Read the `PORT` from the system environment if it's present. This is
related to #44 and will make the port read order this:
1. `-p` flag.
2. `PORT` in the `.env` file
3. `PORT` environment variable
4. 5000 as default port
This serves two purposes. It protects with a Mutex where it was missing
before, and makes it so that there is only one place to change code for
the line writing, which will be a later pull request.
