add pre tags so whitespace isnt collapsed

[PCSwingle]

Fixed #342. Use <pre> tags to display text so whitespace appears normally; this always means we don't need to replace newlines with <br> tags.

I liked it more the other way. This way paragraphs are all on one line and you have to do a lot of side scrolling.

Oh hmm, I do want it to still wrap. I think there is a way to make it still wrap (as long as there's a breaking character); let me fix that. I do think we definitely want this though, since seeing the whitespace is important (otherwise it could be easy to miss a bug relating to whitespace)

EDIT: When I use the --diff command...

I'm getting these errors from the conversation_viewer when I click on a message to see context. It only happens on this branch but I can't see how it's related. Anyone else get this?

[PCSwingle]

@granawkins could you send me the exact transcript that happens on? I'm not getting this error

Thanks for fixing the wrap! Looks good to me. I can't imagine Grant's error is related though we should get to the bottom of it.

I think the problem is related to the size of the diff - I was using a massive one, but a smaller one works fine. Good to go!
