Configure Tmux to use 1 as its first window index

Tmux will start its first window at index 0, which can be unintiutive when you visually associate your windows with the number row on your keyboard. i.e. your first Tmux window is the last number on the number row (0), and the second window is the first number on the row (1).

This config in ~/.tmux.conf will make 1 the starting index so that Tmux windows and the number row both grow from left to right in an intuitive manner.

# Start windows and panes at 1, not 0
set  -g base-index      1
setw -g pane-base-index 1
