This changes the following items:

- package name is now `blender-3.0.0-git.09eb04c0a865-windows64`
  rather than `blender-3.00.0-git.09eb04c0a865-windows64`
- Fix version resource for blender.exe not building
- Data directories are now `3.0\...` rather than `3.00\....`
- User prefs are now in:
  `c:\Users\users\AppData\Roaming\Blender Foundation\Blender\3.0\`
  rather than:
  `c:\Users\users\AppData\Roaming\Blender Foundation\Blender\3.00\`

  has a special exception for 3.0 to check for 3.93 and older.
