Fix #40. Added commented out shell alias as discussed. I also fixed a nasty shell alias bug which this revealed. It had been previously reported at https://drupal.org/node/1967346. I used str_getcsv() to fix it and that function is not available in php 5.2 so backport to 5.x needs work.
Hide site-reset command as it is removed in Drush 7 and now deprecated in Drush6. Use site-set without an argument.
