When we have something like this: <p>Before <?FM stuff?> after.</p>

the paragraph is sent as two separate text units instead of one with the Pi as inline code.

We also don't allow comments in the middle of a segment. I guess these would be treated as normal inline codes.

added two test cases for inline comments and PI's in HtmlEventTest. Made needed changes in Html, Markup and TaggedConfiguration classes.
