refactoring
The fact whether the registry value was a regular or an expandable string is now propagated up to the `Environment` module (and even further to the apps). This was done to get rid of these weird `setString*` functions (and the like). I don't feel like I've came up with the right abstractions yet though, so there's more work on this to come.
