Simplify getting started page

[richardhodgson]

• short explanations of each project
• concise hello world
• expanded tutorials showing get/post

(bloody gorilla testing ;-)

Ok, I've added http://use.no.de/getting-started/what-does-what for the first bullet, and cut down the /getting-started page considerably.

I've got a more expanded example page started but not finished... was thinking a simple todo list app would be good.
