All "int" declarations stripped away from doc snippets

From: http://developer.qt.nokia.com/forums/viewthread/8860

Just open any doc page which contains a snippet where you declare something as int: the "int" itself will be missing.

F.i. the main functions (and its argc argument) here

The same, plus the "int" as 1st parameter of the Q_ARG macro
