Flickable: Use increased default flick parameters on BB10
Due to the high resolution the display default flicking speed
is rather slow. This change introduces increased values of
QML_FLICK_DEFAULTMAXVELOCITY and QML_FLICK_DEFAULTDECELERATION
which feel closer to the native experience.
Also cleans up the flick variables a little by moving them to
their own header, so that QQuickPathView can also benefit from
the improved behavior on BB10.
