Subject: [PATCH] This fixes the issue where the installer deletes the User
 folder, possibly including saved-games, and deletes everything else in the
 install folder, possibly including games that took hours to dump.

We still delete the Sys folder though, because otherwise games will use the wrong settings due to our wildcard support. And we delete the Languages folder, any DLL files, uninst.exe, Dolphin.exe, DSPTool.exe and the qt.conf and cpack_package_description.txt that older Dolphin installers or packages accidentally create.
