ChangeScreen2: Narrow reply button header spacing

Setting the min width of the reply button in the CS2 header pushes
the change status so far to the right that it gets cut off by the
Patch Sets drop down for some screen resolutions.  The change status
also has a 22px left margin, so there is still space between the two
widgets.
