Added a new general user preference by which the
display order of the patch sets in the
ChangeScreen can be reversed so that the latest
patch set is always shown on top.
If there are a lot of patch sets for a change the
latest patch set and the links to the diffs in the
patch set are below the fold of the ChangeScreen.
In most cases users are interest in the latest
patch set. This is why it may be more convinient
if the latest patch set is always displayed on
top.
