theme: redo scroller theme of elm

Summary:
this was a little bit weird. There was a script that did what we already
do in C and pass it on via signals, however, there was also somewhere a
bug in this script, the arrow was not getting enabled, even if the
position is not completly max and not completly min, the problem here
was that the numbers that are passed to edje are not 100% correct (I
think they got somehwere on the way casted to an int).

With this commit we just use the signals from c in the theme and replace
the theme, this should also make everything a bit easier on the
mainloop, as a single movement of the scroller does not schedule 10
timers anymore.
