Feature request: Don't create subfolders when trying to run a nonexistent game

[Vagankovo]

Currently vkQuake creates subfolders together with corresponding config.cfg files inside the Quake directory when trying to run a nonexistent game or mod. I consider this to be an issue, as we all sometimes make typos when launching the game from CLI and that adds in work to clean up the Quake directory. On top of this, I see no benefits to this (although I may be wrong). As such, I suggest removing this behaviour.

Consider reporting this upstream to QuakeSpasm. Not sure if I want to break their behavior.
