- most of the things in utils/ are in the CalamaresUtils namespace, let Permissions follow suit. Chase the name change in the *preservefiles* module. - add an `apply()` function for doing the most basic of chmod. Note that we don't use `QFile::setPermissions()` because the **values** used are different (0755 for chmod is 0x755 in the enum value passed to `setPermissions()`).
