Thirdsphere Update

Made a few small updates to ThirdsphereNet:
  1. Posted some CSS code snippets for rounded corners and opacity.
  2. Posted some old web templates: Alpha, Gamma, Epsilon (Octagonal Simple), and Tekniq.
  3. New poll to choose what I should base Thirdsphere's Spring '01 Masthead on.
I'm still debugging the downloads section, so that is still unavailable.
