WikiNode project

Mattis Manzel has brought to my attention the so-called WikiNode project. The basic idea is that every wiki should have a page called WikiNode, which describes what the wiki is about and provides links to the WikiNode pages of related wikis.
I have added a WikiNode page to both of my wikis, Crazy Hacks and Unmaintained Free Software (besides other new stuff such as a forum, image license templates and more).
