Highlight errors in messages section

I had a module which was not compiling and it took me a long time to understand why I could not load it in the REPL. Could you please highlight the error word in red or something equivalent to make it obvious there is an error? See example here:

I've tweaked the stylesheet in v0.9.6 a bit, which should hopefully make it a little more readable. As for highlighting, honestly, at some point you have to consider figuring out that ide-haskell thing, since, you know, error highlighting in editor, go-to-error, more-or-less properly highlighted error messages, stuff like that. I'm really not keen on reimplementing all of that in ide-haskell-repl, that would be pointless waste of effort in my opinion.

@lierdakil It would be very useful even if you would just color the word error so it stands out. I have lost quite a lot of time because the error was not obvious. So it definitely sounds like something that would be useful for the users and improving the UX.
