Preserve paragraphs in comments

[tom-sherman]

We're saving comments with newlines in the db but just discarding them by rendering the comment to a single text node.

This is mostly just a quick stop-gap fix until we get proper rich text editing.

This needs more thought...

[tom-sherman]

So i think we should:

• collapse duplicate newlines on the client when you submit eg. \n\n\n\n\n -> \n\n
• use whitespace: pre-wrap to render them
• implement a collapse/expand mechanism for long comments (we need this anyway for real long comments)

[tom-sherman]

Decided not to do truncation, at least for now. Reddit doesn't truncate and I think truncating would encourage shorter form comments which isn't something we probably want to encourage.
