Add config for mackup

- ignore apps whose config files are in the `dotfiles` repo
  (see: https://gitlab.webartifex.biz/alexander/dotfiles)
- include various (config) files that should not be public:
  + Cisco's AnyConnect
  + history files for `bash`, `less`, `python`, `psql`, `tig`, and `zsh`
  + Nautilus' bookmarks
  + SSH config & known hosts
