Fix #204

[jindraivanek]

Attempt to fix #204.

Problem in integrateComments was that block comment was also part of newTokens.

See also #217.

Please could you explain a bit more about how you discovered and solved the problem? I've gone through your PR. What exactly do you mean by "Raw Comment"?
Thanks in advance

I put breakpoint in place where first "(" occurs (https://github.com/dungpa/fantomas/blob/master/src/Fantomas/TokenMatcher.fs#L589) and then follows what happens next. Turns out that alg got out of balance because on top of newTokens is Comment tokens, which is case that is not considered at all.

What I did, is in case of comments in newTokens just output it, while throwing out matching token from origTokens (assuming there is same comment token).

RawComment naming just follows used naming of things in newTokens, for example RawDelimeter or RawAttribute.

Thanks for the good work. Sorry for the delay.
