Now qs60style does not send extra resize event in orientation change.

QSymbianControl::HandleResourceChange contained global event handling.
So Qt handled same issues unnecessarily (for each shown top level
widget). Now this global event handling is encapsulated to
s60ResourceChange (new method) called by s60main. In addition,
qs60style generated unnecessary resize events. If widget was
fullscreen or maximized, then this caused incorrect resize events
(old size delivered). With these changes, qs60style just informs
widgets of style change (similarly as in qstylesheetstyle).
