Comment POST action goes to page where the partial is embedded

[ashleybroughton]

We're currently handling POST requests from the CreateComments component in the page where the component is embedded. e.x. https://github.com/csharpfritz/CoreWiki/blob/dev/CoreWiki/Pages/Details.cshtml.cs#L87-L108

Shouldn't we be handling the post of the comment creation in the Comment component? Or if not there, somewhere other than the embedded page?

Just trying to stick to the single responsibility principle.
