Title: Fixing some italics syntax consistency issues

* Added skipping escaped italics tokens when end matching
* Updated prefix/suffix constraints for start/end patterns to be more consistent with behavior of the Markdown Dingus
* Added constraint on start pattern so that it doesn't match if there isn't an end token within the same paragraph
* Added sample.md to syntax dir to use for testing syntax consistency w/the dingus
