Allow RSS feed to display either full post or the excerpt

[naepalm]

I couldn't find this anywhere, so I thought I'd make an issue - it would be really great if we could select whether we want our RSS feed to populate the full post or just an excerpt of the post.

Have fixed this and #71 :)

You can follow the instructions here: https://github.com/Shazwazza/Articulate/wiki/Configuration#rssfeedgenerator

This will allow you to configure the RSS feed however you would like.

If you want to just display the excerpt then you can override the GetPostContent method of the RssFeedGenerator and do this:

 return model.Excerpt.ToHtmlString();
