Finishing tutorial

Hey there!

As promised when I was in Berlin, I actually did go through the tutorial and extended it so it doesn't end too abruptly - finished the part that ended in the middle of a sentence and a simple view/template for the Poll content type. I also went through the first part and updated it to the latest Kotti version (fanstatic vs static etc.). 

Tried to keep it readable and clean, but my writing style is of course different then yours. Feel free to change anything (or comment and I'll try to change it to be better / more appropriate when I get the chance).
