Fix #1 - Remove short array syntax for compatability with PHP 5.3

If you are running PHP < 5.4, you will receive an "unexpected '['" error. Reverted back to array('key' => 'value') from the short array syntax ['key' => 'value']. Should now be 5.3 compatible. Note: I also initiated a pull request for JeffreyWay/Laravel-4-Generators repo to fix the same issue. As far as I can tell, it solves #1. Thanks!
