Issue:
Turn off comments by default
There are some cases when including with `comments` enabled breaks the content. At least:

- #192

Might be worth to change the default value to `false`. I think that so much people doesn't even know that there are comments added by default and are not worth if they are breaking some includes.

Pull request description:
Set `comments=false` as default for `include-markdown` directive
Closes #194
