A new scheme with merging the changes of properties. A new scheme  is the result of development of an undo in collaborative editing of a document. The changes of properties for classes Paragraph, Document, TableId now can be merged.

Undo/redo functions are working with both types of changes like an old object and like a new classes.

All changes for class ParaRun were reworked in to a classes. Also added a scheme sketch for Undo/Redo for fast collaboration.

Added base classes for changes in collaboration. Started to rework collabotation changes into a classes for class ParaRun.
