Reduce usage of qApp in favor of static function calls

Q*Application classes have unusually many static functions. In many
cases in our code, these functions are unnecessarily called as instance
functions, using the qApp helper.

This patch replaces many occurencies of qApp with the according
Q*Application classname.
