Title: Automatically change directory to last file opened

`set autochdir` allows you to open a file in another directory:

:vsplit ../../models/foo.php

And when you're working in foo.php, you realize you need to make a
change to the bar model, bar.php, you can simply do:

:vsplit bar.php

Instead of having to do:

:vsplit ../../models/bar.php
