Even though directly closing the socket is not very neat in the
architectural sense of things, it allows the best of both worlds: the
socket is instantly closed and is open for reuse while the listener struct
is still available as a reference.
This change needs to be revised when the listeners are refactored into
separate objects.
Updated documentation to reflect the change in behavior.
MaxCtrl now supports explicit paths for certificates and optional server
certificate verification. This allows testing by using a self-signed
certificate with the server certificate verification turned off.
Using commas instead of spaces prevents a the misinterpretation of
commands as hostnames. If the `--hosts` option was given just before a
command, it would consume the commands as arguments to the `--hosts` list.
Updated documentation generation script and regenerated documentation. Now
all command documentation is generated by using the output of the `help`
commands.
