Language and config files become folders if they did not exist before

Forgive me for interrupting you again. :)
Maybe it will work
```
    "pre_install": [
        "function CreateFile ($name) {",
        "    if (!(Test-Path \"$persist_dir\\$name\")) {",
        "        New-Item -Force -Path \"$persist_dir\" -Name $name -ItemType \"file\"",
        "    }",
        "}",
        "'SearchMyFiles_lng.ini', 'SearchMyFiles.cfg' | % {CreateFile $_}"
    ]
```
