Packages should be downloaded to e.g.`~/.cache` on Linux instead `/usr/bin`

Looks that when I open project in Godot Editor via /usr/bin/godot, then when I trying to download installer I always got error message

ERROR: [14:16:48.587] [error] Failed to download cdda-linux-tiles-x64-2021-09-11-0808.tar.gz.
   at: call (modules/gdscript/gdscript_functions.cpp:774)

This is probably caused by permissions problem. I think that files downloaded files should go to .cache or similar folder

Ha, it didn't occur to me that this would happen, since I never installed Godot through a package manager. It is best to download it directly from its website (it is one self-contained executable), since you often want to stick with a specific version for a given project and don't want it to change on you uncontrollably.

Catapult by design creates all its files next to the executable, for portability. When you run a project from Godot Editor, the editor itself is the executable, so when Catapult checks what directory it's in, it gets /usr/bin in your case. I don't know whether to view this as a legitimate issue that needs fixing, since it is not a problem with the end product.

That said, maybe it would make sense to check if the directory is writable on startup and fall back to ~/local/share or %LocalAppData%.
