Add a new hello world plugin and adjust the welcome message.

[stacey-gammon]

I've gotten some feedback on the Developer Guide that the order of the documentation doesn't work well because it jumps into advanced concepts too quickly.

I decided to try to follow the React Docs which has a hello world plugin as one of the first things a user will read. I also created a Contributing section, as they have, and moved some of the Getting Started content into that.

After:

I'm also considering renaming tutorials to Advanced Guides ala React as well.
