[CIUv3] Custom Installer Ultimate v3

[Proxson]

Ok guys,

so here is the problem when using external scripts like custom icons, shortcuts and the Registry script. When uninstalling the game,
it does not remove the Program folder in Start Menu and the Registry keys still remain despite the game is uninstalled. If you have time,
please implement this option. Here is the script. Please try it. Thanks.

Edit: I managed to delete the program folder in Start Menu -->

[UninstallDelete]
Type: filesandordirs; Name: "{userprograms}\{groupname}"

Edit 2: Nope, it doesn't work always. Weird behavior. @.@

/me embarrassed...

Well, the Registry entries "issue" is still there.
