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.
