add links to jump to the results page for each package

[pabs3]

Sometimes when I'm looking at the results I can see that the results for a package aren't useful for what I'm searching for. Currently I have to click through each of the pages of non-useful results for that package. It would be nice if I could just jump to the page for the next (or previous) package. I guess this would incur extra resources, but hopefully it wouldn't overload the service.
