Refactor project to new name

The name of the project is being refactored from Privacy Revolver to
Farside. The reasoning behind this is:
1. A shorter name is easier to remember
2. It can stand for "FOSS alternative redirecting service" (which I know
doesn't encapsulate all letters from "farside", but it's close enough).

This commit also includes improvements to the update script for
determining how far along the script is.

+- Install [redis](https://redis.io)
+- Install [elixir](https://elixir-lang.org/install.html)
+- Start redis: `redis-server /usr/local/etc/redis.conf`
+- Install dependencies: `mix deps.get`
+- Initialize redis contents: `mix run update.exs`
+- Run Farside: `mix run --no-halt`
