Make homebox exportables more standard

Hi,

Homebox is exporting homeboxes in arrays, and the arrays are defined thus:

      'gateway_user_topic_block' => array ( 
        'module' => 'gateway_user',
        'delta' => 'topic_block',
        'region' => 1,
        'movable' => 1,
        'status' => 1,
        'open' => 1,
        'closable' => 1,
        'title' => '',
        'weight' => -36,
      ),

There is a space between 'array' and '(' but the coding standards (https://drupal.org/coding-standards#array) show there should not be a space. This is picked up by coder_review.

Also, is there a reason the module doesn't use features_var_export()?
