Compatibility issues

To use equation objects with the free version of Adit Math engine, RVBasicMathWrapper must be included in project.

Some functions and constants were moved in another units (RVCoordFuncs, RVColorFuncs, RVClipboard).

When TRVStyle.MainRVStyle is assigned, not only StyleTemplates, but all properties of TRVStyle are shared (except for collections of text, paragraph, and list styles).
