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.

Classes CMathContent/CMathBase/ParaField are now inherit from a new class CChangesBaseContentChange.

Added a new base class CChangesBaseContentChange. Content changes for classes  Document/DocumentContent/Hyperlink/Paragraph/Run/Table/TableRow now inherit from this class.

Class ParaTextPr was moved in a separate file. All changes for class ParaTextPr were replaced with new classes.

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.

Reworked constants for history. For now all constant for type of class - is 2 high bytes long values, constants for changes TypeOfClass | TypeOfChange. So from now by a type of change it is possible to get a type of class.
