Problems with zsh installation

I cloned your repo under my home and make the bin executable and add the following settings in my `~/.zshrc`

```bash
export PATH="~/.tmuxifier/bin:$PATH"

if [[ -d "$HOME/bin" ]] ; then
  PATH="$HOME/bin:$PATH"
fi

eval "$(tmuxifier init -)"
```

When reloading the shell I got the following error:

```bash
/home/wikimatze/.zshrc:155: command not found: tmuxifier
```

The workaround to this issue is get rid of tilde in the export path and give the absolute path:

```bash
export PATH="$HOME/.tmuxifier/bin:$PATH"
```
