ID#209 remove unnecessary doc tags
since PHP 5.3 introduce more language features for OOP we don't need some phpDoc-Tags
anymore and remove them. Good IDEs and doxygen recognize the features from the code.
This includes the following tags
  @private
  @protected
  @public
  @static
  @abstract
  @package
  @class
  @interface
correct phpDocs
- remove @desc and @const because they are not phpDoc standard
  and therefore not recognized by IDEs and Doxygen
- corrected phpDocs to be better recognized from IDEs and Doxygen
  - the first lines in phpDocs must be the description of the
    method/property/class whithout phpDoc tags
  - to document a property or constant in doxygen its is necessary
    to write the phpDoc like that
	    /**
	     * description of property
	     *
	     * @var type $propertyName
	     */
    	protected $propertyName;
ID#217: re-arranged the license header.
