Use [NSEvent characters] to retrieve the input character.

This is how it was done in Qt 4.

An issue with the current approach was that it did not consider
modifiers when setting a Qt::Key_* value, which would assign the same
Qt keycode for:

a = a(65)
Alt + a = ā(65) [here it should return a unicode value for 'ā']

This is inconsistent with the other platform plugins.

Also in the combination with a dead keys it was returning nothing in
the output.
