/**
* @brief: Get info header of the scheme
*
* This function parses the header of the schemename.php file for informations 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 scheme.
* All color variables which get overwritten through the theme have to be
* listed (comma separated) in the scheme header under Overwrites:
* This seems not to be the best solution. We need to investigate further.
*
* @param string $scheme Name of the scheme
* @return array With theme information
* 'author' => Author Name
* 'description' => Scheme description
* 'version' => Scheme version
* 'overwrites' => Variables which overwriting custom settings
