snn ec96437207 0028564: Support of applications using old persistence (ShapeSchema)
1. Bug fix in reading old persistent data using FSD_File storage driver
2. Persistence compatible with legacy format was restored for shapes
   a. Implemented a storage read / write wrapper for legacy persistence
   b. Added DRAW commands to read / write files in legacy format
   c. Added test cases for reading / writing operations with checking number of sub-shapes and physical properties
   d. Updated related sections of the development guide
