Archit Gupta 4e9f53ff4e Enable all options to be auto-loaded from nixDir
This removes the manual configuration of which options are auto-loaded.
Now all options are eligible except for "nixDir" and "_module" as those
would cause inf recursions.

Additionally, instead of setting name aliases in the nixDir module, a
config option is added, enabling other modules to extend the aliases
lists.
