Title: Update wp-less.php

If I run composer on the plugins directory everything works as expected.

However, if my site has a composer.json, and this plugin is specified as a dependency, the vendor folder is in a different location, and the require fails. So instead, load the autoloader if it's present in a vendor folder. If it isn't, then assume it's been included somewhere else.
