Draft Installation Instructions for YOURLS

[Tim Flink]

Since we're going to be deploying AutoQA 0.7.0 soon, we need to have
documentation about the new features.

I've written up some installation instructions for YOURLS to be used in
AutoQA. I'd appreciate comments and a look over to make sure that I
didn't get anything wrong.

Thanks,
