File / directory structure change from 5.0 to 5.1:

Table handlers "bdb", "heap", "innobase", "myisam", and "myisammrg"
have been moved into a common subdirectory "storage".

This must be reflected in the tools for Windows:
1) When the source package is created, there is the additional level "storage".
2) The project files below "VC++Files" also get that additional directory level, to keep structures in sync.
3) Within the project files, references to/from the table handlers must cross that level.
