PHP 5.4 array syntax

[augsteyer]

Was running the code on PHP5.3 and got an error in my logs:

[Thu Dec 07 05:19:10 2017] [error] [client 127.0.0.1] FastCGI: server "/usr/lib/cgi-bin/php5-fcgi" stderr: PHP message: PHP Parse error:  syntax error, unexpected '[' in /var/www/mage1810/lib/Module/cloud-integration-magento-oauth2/vendor/bshaffer/oauth2-server-php/src/OAuth2/Server.php on line 91

These are the php5.4 syntax culprits:

/**
     * @var array
     */
    protected $grantTypes = [];

    /**
     * @var array
     */
    protected $responseTypes = [];

Based on the required composer version of php 5.3.9, I am assuming this is a bug.

hmm seems like @bshaffer forgot to remove php 5.3 support in #869 not sure what to do now. removing support now will leave old users with a broken latest version that supports php 5.3.

but @augsteyer maybe time to update your php version? php5.3 is almost 4 years is not supported

I believe this is the only thing that keeps this from being 5.3 compatible. Easier to switch these two to = array(); and retain 5.3.9 support, no?
Also, when working with 100k+ merchant systems, it's not that easy to tell everyone to upgrade their php. Merchant's are risk aversive bunch and would rather avoid our plugin than upgrade their system.

This has been merged into master. Thanks for the fix!
