Moved articles/features to Wiki

I setup a Wiki for my articles so I can easily edit them and so others can make corrections and additions (such as in the ThingsWrongWithPHP section). The Wiki is available here (or use the Wiki tab). For those that don't know what a Wiki is, a Wiki is a website that can be editted by anyone using very simple codes. A change log of each entry is kept so reverting to older versions is very simple. Maybe the most useful and well known Wiki is the WikiPedia which is the biggest encyclopedia in the world already.
