[Diaspora] Cluster Generator

[Gordon McCormick]

Since my Diaspora book is out on loan to one of my group, I was bored
and decided to create a cluster generator:

http://sprucemoose.net/cgi-bin/cluster

Just put in the number of systems you want and optionally names for
each of the systems and it will generate a (hopefully nice looking)
graph. Hit reload if you want something different. T2 and higher
systems are in red.

Let me know if there are any bugs!
