* @brief: Get info header of the shema
*
* This function parses the header of the shemename.php file for inormations like
* Author, Description and Overwrites. Most of the code comes from the Addon::getInfo()
* function. We use this to get the variables which get overwritten through the shema.
* All color variables which get overwritten through the theme have to be
* listed (comma seperated) in the shema header under Overwrites:
* This seemst not to be the best solution. We need to investigate further.
*
* @param string $schema Name of the shema
* @return array With theme information
* 'author' => Author Name
* 'description' => Schema description
* 'version' => Schema version
* 'overwrites' => Variables which overwriting custom settings
