As a user, I want to download content to a local folder, so I can read the pages offline.

• Specify dedicated downloads location
  • Windows: C:\Users\<name>\Downloads\Grey-box\ or C:\Users\th8795\AppData\Local\Grey-box.
  • Linux: $GREYBOX_HOME/, $XDG_DATA_HOME/Grey-box/ $HOME/.local/share/Grey-box, or /home/<name>/.local/share/Grey-box/, depending on environmental variables and all that.
  • Mac: /users/<name>/Downloads/Grey-box/
• Ensure that we have permissions to read and write to this directory
