Ilkkal - GameEnabler example matrix flipping

Hey, there are a few comments and a couple of for loops in the GameEnabler examples that talk about needing to flip the rows and columns of QMatrix4x4's before feeding them to OpenGL. The way the arrays are indexed, it does not in fact flip the matrix but is a NOP. At least on Maemo 5 PR1.3 the example works exactly the same when you just feed matrix.constData() to glUniformMatrix4fv(). (I'm commenting instead of editing because maybe there's a really really clever reason for the code?)
