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 some phpDocs and format code
- 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
  - the first lines in phpDocs must be the description of the method/property/class whithout phpDoc tags
