QList: fix regression in swapItemsAt

Browse Source 
Commit e0d2b50249839d10ecf87abc296b8020046d1d75 makes swapItemsAt
use ADL to find swap(). Problem is, QList has a swap() function
(that swaps the elements at the specificed _indices_); that function
will be found before ADL kicks in.

So do the second best thing: use qSwap instead.
