Don't make primitive return types const, since that causes warnings with GCC.

Non-POD types, it may make sense to avoid having people use it for something 
that discards changes. E.g.

	// the functions return QDateTime, and QString
	QDateTime dt = getSomeDate().addDays(30);
	QString s = getSomeString().append(" World");
	getSomeString().push_back(" World");

Without "const", all three compile. Two of them are useful, one is useless 
(which one?).

With const, only one compiles (can you tell which?). Of the two that don't 
compile, one would be useful to have compiling.
