Draft: Added Quest Editor and general update
Fixes #2.
AppId is changed from org.solarus_games.solarus-launcher
to org.solarus_games.solarus
, as it now contains both the launcher and the quest editor.
Also updates to Solarus 1.6.5 and libmodplug 0.8.9.0.
Flagged as Draft in case it breaks on Wayland, as I did not update the existing Wayland-specific patches.
