[Development] qHash / QHash changes

[Giuseppe D'Angelo]

So, after *too many* commits[1] -- QHash randomization was merged a
few hours ago!

https://qt.gitorious.org/qt/qtbase/commit/c01eaa438200edc9a3bbcd8ae1e8ded058bea268

Thanks to all of the guys involved for the ideas, feedback, reviewing
the patches... and staging them :-)

Cheers,
