propagate a negative score point along breaks/conflicts
versioned -dev packages like db and boost have the problem of no dependencies which would give them a competitive advantage against an older incarnation of the -dev package, so they tend to be kept back until the old version is removed from the archive, which, if the user has older releases in its sources can take a long time (or never happens). The newer version has a conflicts/breaks against the older one, but the older one hasn't against the newer, so by giving via the conflicts the older one a reduced score the newer one can win if there is no other reason to keep it. If both have a conflict against each other the scoring will cancel itself out, so no harm done. This gives "action" a slightly bigger edge in breaks/conflicts cases than before, but holding back isn't a really good solution anyway.
