Backup all mods at once

[darekkay]

I've extracted the task mentioned in #11 to enable downloading/backing up all mods at once.

Here's my current workaround (using Git Bash/MINGW64 on Windows). The script goes through all Workshop JSON files and calls tts-prefetch followed by tts-backup:

#!/usr/bin/env bash

MODS="$HOME/Documents/My Games/Tabletop Simulator/Mods/Workshop"

find "$MODS" -name "*.json" | while read file; do
  tts-prefetch "$file"
  tts-backup "$file"
done

Perhaps we could allow passing a directory name on the CLI and then load everything from there. This would also address the problem mentioned in #13.
