Merge pull request #243 from adityab/filter-annotations

Make positioning around annotations more usable/realistic
* Add moveCursor flag to OpSplitParagraph.
* Adapt places where OpSplitParagraph is initialized
to also add the moveCursor flag.
* Let SplitParagraph vs SplitParagraph execute normally
at the same position.
Adapt tests to work with the new SplitParagraph behavior.
Also add a test to transformationtests.xml to check for
correct behavior whilst splitting at the same position.
