[Feature Request] UI folder icon, Docs and plugins

[ninjaloose]

• Addition of a small folder icon to the left of the "Play" button, so that the folder is easily found and opened, this would help for integrations into Steam or Playnite etc.
• It would also be nice to specify where these files were installed in the first place.
• Helpful if there was some documentation on how to setup/use this Launcher in the OpenRCT2 docs It is not mentioned at all. It was easy personally, but many fear the unknown. It looks to be a nice way to keep OpenRCT2 upto date. I will make a fresh guide on steam soon.
• Perhaps upgrade this tool to install, check and update the plugin versions too.
• If there are any CLI arguments such as --update or --play OpenRCT2. They would also be useful for Playnite to Steam automation.
