Prevent blog post JS from appending other content in the div

[Riot]

i.e. below the blog post includes rather than above them

Renamed issue for clarity, the issue is that the callbackFunc(feed) function is appending to content after whatever is already in the div, which causes anything you put in to appear to be prepending the blog.

Move blog posts to a separate div and add a loading state, resolves #3
