Win32 Installer: It should NOT delete files that it doesn't create
Example:
- Create this file => C:\Program Files\VideoLAN\VLC\lua\extensions\test.lua
- Install VLC 1.1
- Uninstall it
You can see that the file test.lua is deleted, and it is very bad. Tested on vlc-1.1.0-git-20100311-0002-win32.exe
