Spatial, spatial, spatial

I've posted a whole bunch of spatial computing stuff on my page this time. There's links to the upcoming
Spatial Computing Workshop (submission deadline July 10th,
special issue on spatial computing in ACM TAAS (submission deadline August 1st), and the spatial computing community home page.

In addition, I've posted my talk about functional blueprints from the Morphogenetic Engineering Workshop, our DCOSS paper with gradient self-stabilization proofs, and the PACEM whitepaper on how to use spatial computing for painless energy demand management in a smart power grid.

I've also reorganized the page to put key links and spatial computing up higher, and edited the text some.
