feat(appid): Add auto appid detection to other launchers (#17)

* feat(appid): add auto detection for Ubisoft Connect and Heroic AppIDs

* chore(appid): cleanup the code and auto make folders for non steam AppIDs

fix: make kscreen command dynamic/variable defined (#16)

feat: implement SCB_APPID env var

overrides the automatic APPID detection for steam (hopefully this can be extended to support heroic, umu, lutris in the future)

All AppID configs are stored in ~/.config/scopebuddy/AppID
the root is for steam
any subsequent launchers will be nested under this folder
example: ~/.config/scopebuddy/AppID/lutris/somegame.conf

usage: `SCB_APPID=lutris/1337 scb -- %command%`
result: loads the global config defined by `SCB_CONF` then sources `~/.config/scopebuddy/AppID/lutris/1337.conf` which overrides anything set by the global config

Part of supporting #10
