HTML Preprocessing

I replaced the PHP in wingchun.stanford.edu with static HTML. To avoid repeating code I used GPP, a generic
preprocessor.

I initially selected PHP for all my webpages because I had grandiose plans to build exciting dynamic sites. It never happened, but I kept the PHP in case I came up with some ideas. The development cycle is also one step shorter, and I don't get enough traffic for the performance hit to matter.
