Making Keypad Navigation more usable

All changes of this commit are #ifdef'ed in
QT_KEYPAD_NAVIGATION. Most desktop Qts won't notice
any change.

Navigating between QWidgets was not alwys a pleasure on
keypad devices. This commit fixes the navigation behavior
for some widgets, mostly itemviews.

Furthermore, it adds a 'directional' navigation mode. Until
now, the existing keypad navigation used the tab order
do go back and forth between widgets. The new mode is supposed
to provide a more intuitive navigation. It is the new default
mode on Symbian.
Screens (and their resolutions) become bigger, and also low
resolution screens can be used in landscape mode. That's
why the directional mode was requested.

Another popular request was to put some more convenience into
QSlider: If a (horizontal) slider has focus and the user presses
left/right, the value of the slider may directing change
without being selected (edit mode).

This commit also adds the manual test 'keypadnavigation'.
