Closes #131

@amazeika I did by chance upgrade to 1.6.0 the other day, when it was available... it broke my console commands:

joomla site:list
PHP Fatal error:  Uncaught Error: Class 'Joomlatools\Console\Command\Configurable' not found in /home/vagrant/.composer/vendor/joomlatools/console/src/Joomlatools/Console/Command/Site/AbstractSite.php:18

Steven identified the problem as being the lower case nature of the file name:

Configurable.php not configurable.php

@amazeika I'll give this another spin again today, excited to give it a whirl!

@yiendos Yes, it Ercan tagged it by mistake, now it's good. I also fixed vhost:alias which was broken. The loader issue with configurable wasn't a problem on my end for some reason ... please let me know if all is good now.
