Suggestion / Bug Platform

In a similar way that we are prompted for the default theme when labymod is first installed, we should be prompted for our minecraft folder directory.

If we installed minecraft in a different folder location, labymod will crash after the theme selection but before the main launcher screen, where we have access to that setting (so we don't have access to it). Which makes it hard to use labymod for the first time if we don't have a standard minecraft folder location, since we have to figure out where the config file is to change the setting and be able to start labymod.

Furthermore, it would just make sense to be asked all required settings on first install, like it is already done with the theme selection.
