Right now, LeProxy requires being run from the command line in order to spawn a new listening socket for its proxy operation. When not run from the command line, it will currently report an error and exit (#26).

Once LeProxy has a web interface (#52), there's an increased chance that people will not run it form the command line, but expect it to work from common web servers, such as Apache, nginx, php -S and friends. We should at least provide some limited support for this and at least provide some basic instructions to set up LeProxy.

In the future, we may want to provide some limited functionality in this web mode, but this is out of scope for this initial feature.
