Add hardcoded default applications list taken from online.gnome.org

The previous list of all applications in a random order was obviously
temporary.  This patch improves things by adding a static list, taken
from the online.gnome.org/applications data.

In the future we will either have a vendor-chosen static list, or
a fully dynamic system.
