Æsthetics: Icon for dynamically generated pages

Created an icon for the dynamically generated pages in a new {\tt winicon} directory and added a {\tt link} reference to it in the standard XHTML header.

I think a nice looking Eat Watch icon similar to the one used for the Palm application might be better, but I'm in hack mode, not art mode at the moment, so this'll have to do for the nonce unless somebody contributes a better image. (The icon needs to look good at 32×32 pixels with 16 colours, and should also “work” in 16×16 pixels 16 colour and 48×48 pixels 256 colour modes.)
