Solarus GUI System-wide Config
Related to the original use case of #947 (closed). Installing a package to the launcher works, but during package installation, the quests get installed to root's config (sudo solarus will show the quests, but not just solarus). I'm not sure what the alternative location would be on other systems, but ideally the system-wide config could go in /etc/solarus on Linux.
