UI: Enable viewing and sorting the packages list by the type matching. Also display in details

[pombredanne]

I would like to view and sort the PurlDB matching type of a package (either based on a package archive match or resource or else). This is useful to sort and navigate through packages in the packages list; and this is a useful data point on the package details page. When a the resources are matched instead of the whole package or where there are multiple types of matches, these should be summarized and displayed both in list and summary. Having a filter dropdown on the package list for this new column would be great too.
