Go Packages

The Go Packages Fathead fetches the list of official packages that you can import from http://golang.org/pkg/. It currently handles disambiguations (typing in "template" should give both "html/template" and "text/template"), and it can also understand the shortened package names (typing in "url" should redirect to the "net/url" package).

There is definitely room for improvement such as fetching the different functions and types and constants within those packages, but that is probably another project on its own.
