So I've got an initial thing working for the version histories now. You
can construct a URL like [1], which will show a table about the known
versions of the package (icecat in this case) on the master branch.

1: http://data.guix.gnu.org/repository/1/branch/master/package/icecat

The same data is available in JSON [2], and that might work for getting
the data in the hpcguix-web service.

2: http://data.guix.gnu.org/repository/1/branch/master/package/icecat.json

Fetching the data for individual packages definately won't work well for
all applications, so I'm definately open to exposing the data in other
ways as well.
