Simplify NavigationModeKeypad cases
Simplify NavigationModeKeypad cases

Basically, QFileDialog on Desktop performs heavy event handling tweaks
on the lineedit and listview to make them ultra keyboard friendly.
We added many "anti"-hacks for Keypadnavigation to restore the native
behavior of the widgets. The result is pure unmaintainability.
(I admit that most of these "anti"-hacks were my fault, since I
participated in some and reviewed all of them)

This commit has results in the same native behavior for Keypad
navigation but without having the #ifdefs inside the event handling
switches.

Only one of these switch-#ifdefs was there before and still is.
embeddedlinux and wince should still be fine and without unintended
behavioural changes compared to Qt 4.5, since the
Qt::NavigationModeKeypadTabOrder case stays unchanged.
