Apply PSR-2 of PHP Framework Interop Group (FIG)

Change ATKs coding style to an widely used (CakePHP, Composer, Doctrine, Drupal, TYPO3 Flow, PEAR, phpBB, phpDocumentor, SugarCRM, Symfony 2, Yii framework, Zend Framework 2) standard. The coding style of ATK is hard to read, something "custom" (in a negative manner) and not contemporary anymore (2-space-indentation).

These changes are made completely by NetBeans batch source formatter. According to this, "SHOULD" rules, which depend on human interaction, couldn't applied perfectly (i.e. smart multiline-indentation of long parameters). Future development should follow PSR-2 and all other accepted standards of the FIG (especially PSR-1!). You can find more information and the actual standards at http://www.php-fig.org/

The standards (naturally) don't apply to external frameworks/applications (e.g. Smarty) used by ATK.
