appdb request: "Browse Regressions"

[Dan Kegel]

The nice reports in recent wwn's showing changes in
appdb ratings make me want to use the appdb itself
to see which apps have recently fallen in rating.

Following past appdb practice, one would implement
that by adding a new "Browse Regressions" menu
item on the left, below Browse Apps, Browse Newest Apps,
Downloadable Apps, and Browse Apps by Rating.

I expect this will become increasingly useful as
we approach 1.0.  How hard would it be?

(Also, it might be nice to have an "advanced browse"
that let you filter and sort by date, rating, and rating change.
Once that works well, we might not need
all those other specific browse commands...)
