Add links to general gci/gsoc homepages on melange homepage.

Some users may go to www.google-melange.com when looking for information on
GCI/GSOC.  Since the future programs will not be hosted on Melange, we need
a way to point off-site.

Hardcoding the links in the template was the most efficient way given the
available time resources.  It is clearly not the "best" way to do this.
