Little XSS Cheat Sheet added

Since my favorite XSS cheat sheet is down, I decided to compose an own cheat sheet which is a collection of a few sources and based on my personal experience. It is nothing special and does not include the features of other cheat sheets (e.g. browser compatibility, hex conversion etc.), but it is not ment to replace them. It is just a little sheet if you need a fast source for some XSS strings. Enjoy!
