Subject: Added basic nixos module (and restructured some files)

Right now, this is capable of setting up a running instance of picarones
in a couple lines of config (both backend server and the webapp, using
nginx).

More options should still be added, especially to make the backend's port
configurable (but this requires adding features to the haskell code)
