Subject: [PATCH] Add `(nix:$name)` as a prefix to the bash prompt (#191)

* Add `(nix)` as a prefix to the bash prompt

Make it clearer when you're in the terminal vs. not.

* bash prompt prefix: put the project's name in the terminal

* Blame our installer for the nix.conf

* fixup: adding the version to the nix.conf

* force a space after the prefix
