Heronite environment variables (HERONITE_*)

Set these environment variables before you start Heronite. A HERONITE_* switch is on when set to anything except empty or 0.

Change folders and log detail

Variable	What it does
`HERONITE_DATA_DIR=<folder>`	Use another data folder, for a second, separate Collection. Config and cache then go next to it, in `<folder>.heronite/`.
`HERONITE_LOG_DIR=<folder>`	Write logs to another folder
`HERONITE_STEAM_DIR=<folder>`	Where Steam is, when Heronite does not find it
`RUST_LOG=debug`	More detail in the log (`trace` for everything)

Variable	What it does
`HERONITE_NO_UPDATE_CHECK`	No automatic update checks
`HERONITE_NO_TRAY`	No tray icon
`HERONITE_NO_GAMEPAD`	No controller input in console mode
`HERONITE_NO_ANIMATIONS`	No animations
`HERONITE_NO_SINGLE_INSTANCE`	Allow more than one Heronite at a time
`HERONITE_NO_ONBOARDING`	Skip the first-start setup
`HERONITE_DISABLE_IDLE_JOBS`	No background work while idle
`HERONITE_DISABLE_TOOLS_UPDATE`	Do not refresh DXVK, Winetricks, and umu in the background
`HERONITE_WINE_OFFLINE`	No network for the Wine Manager (Linux)

Heronite downloads these store tools. To use your own copy, set:

Variable	What it does
`HERONITE_LEGENDARY_BIN=<path>`	Use this legendary (the Epic tool)
`HERONITE_GOGDL_BIN=<path>`	Use this gogdl (the GOG tool)
`HERONITE_NILE_BIN=<path>`	Use this nile (the Amazon Games tool)

Scripts that run before or after a game, and programs that run alongside it, get these:

Variable	Value
`HERONITE_GAME_TITLE`	The game’s name
`HERONITE_GAME_APP_NAME`	Its id
`HERONITE_GAME_RUNNER`	Its store (`legendary`, `gog`, `nile`, `sideload`, …)
`HERONITE_GAME_PLATFORM`	Its platform
`HERONITE_GAME_EXEC`	The program that runs
`HERONITE_GAME_PREFIX`	Its Wine prefix (Linux)
`HERONITE_GAME_SCRIPT_TYPE`	Which script this is (before or after)

Heronite sets the same values as HEROIC_GAME_*, so scripts written for Heroic keep working. Inside the sandbox, it also sets HERONITE_SANDBOX.
