Fix tmux on Mac

I started tmux. Every time i pressed <BACKSPACE> got got a … space. This felt wrong, so the internets had a solution ready.

This is it:

mkdir -p $HOME/.config/tmux
echo 'set-option default-terminal "screen-256color"' > $HOME/.config/tmux/tmux.conf

Apparently the Mac OS ncurses database on Mac does not contain the settings for tmux’s default value of tmux-256color, but the ones for screen.
