Nette misunderstanding syntax in @layout.latte causes total failure.

When trying to compile ApiGen documentation using the following command, it errors with a PHP ParseError, due to a ";" inserted instead of left as the "," in the original code.

"apigen.php --source ./app --destination docs/apigen --todo yes --title "My Documentation" --php no --download yes --debug"

Added $groupCount variable to templates/{default,bootstrap}/@layout.latte to avoid Nette template framework from misreading the syntax and inserting an unexpected ;
