1346: Move window middle and reset missing [#7498]

[Lowlander]

The Move window to move the video is missing some position markers with the sliders, at least the middle/center position should be shown. Also it would be nice if a Reset button is added to the Move window to reset this specific setting.

Tested on skinned 1346 on XP.
