Lich support

Lich acts as a mediator between a frontend and the server. It just requires a client to be able to specify a host, port, and key on the command line (which Warlock can do), or to be able to connect to a custom server (which Warlock can't do).

As of November 2023, Lich requires a minor change to support launching native frontends on Linux and MacOS, but it works fine on Windows. See this PR for more info: https://github.com/elanthia-online/lich-5/pull/508

To use Warlock with Lich, launch Lich in your normal manner, in the "Manual Entry", pick your character as normal, check "Custom launch command", then enter in the command entry: /opt/warlock3/bin/warlock3 --host localhost --port %port% --key %key% (for Linux, the path for Windows and MacOS will be slightly different). You can leave the working directory entry blank. Hit Play and Warlock should launch and connect to the game.
