Fixes #6 by setting a window option called `vim$TMUX_PANE` during vim
setup, and removing it when vim exits:

```vim
if $TMUX !=# ''
  " Set tmux window option to detect when to change pane.
  let s:tmux_option = '@vim'.substitute($TMUX_PANE, '%', '\\%', 'g')
  call system('tmux set-window-option '.s:tmux_option.' 1')
  au VimLeave * call system('tmux set-window-option -u '.s:tmux_option)
endif
```

Then update the `is_vim` conditional shell statement to check if this
variables exists for the current pane to determine when to change tmux
pane or pass through the binding to vim.

```conf
in_vim='[[ "$(tmux show-window-options)" = *"@vim#{pane_id}"* ]] && \
        [[ "#{pane_current_command}" != zsh ]]'
```

Additionally check if the vim task has been backgrounded by comparing
the value of `#{pane_current_command}`, this is likely a bit brittle if
backgrounding is used heavily but works otherwise.
