Fixes #128 - Parameter to customize min spaces after columns

Add a setting to change the spaces between columns. 

Currently it's forced to 1 space:

	/**
	 * [getItems description]
	 *
	 * @param  [type] $params [description]
	 *
	 * @return [type]         [description]
	 */

With 2 spaces we get:

	/**
	 * [getItems description]
	 *
	 * @param   [type]  $params  [description]
	 *
	 * @return  [type]           [description]
	 */
