Initial brain dump to the touch events wiki

I've just finished an initial brain dump of the things I think are most
important for the touch events community group wiki:
http://www.w3.org/community/touchevents/wiki/Main_Page.

It's obviously pretty biased to the things I've been involved in, and
mostly links to existing resources elsewhere.  Please help expand it, and
feel free to rearrange things to make it prettier and better organized!
