Add proper documentation for creating udev rules for Vial.

I think this is much harder to follow for users not experienced with linux, users and groups. My suggestion is to change the "Generalized udev rule" section to a sequence of shell commands that users can execute, granting them access to the devices - similarly how it was done previously. In this case, you could perhaps use user's primary group (via something like id -gn $USER) by default, and then document it further in sections below.

I made a few changes based off of your suggestions, specifically as to shell commands people could run to get the job done. I just did the simple thing for the time being since it will take a bit to properly write a shell script that won't blow up. The big thing is that I added a udev rule that specifically allows Vial keyboards to have read/write permissions, which should make the Vial experience a lot more transparent.

Another thing, I forced enabled the TOC since I thought it would make the page a lot easier to navigate and find what you need. I don't know how to set up a Just The Docs environment though, so I can't test if I even needed to or not.

Looks like latest changes lost the note about the "users" group, is this actually something that's default on major distros or does it need custom handling?

Not exactly, but safely yes? users is pretty standard from what I know, typically it always refers to gid 100. However, it's not as standard as something like wheel. It's a fairly safe default.

I will work on creating a script that will automatically generate a udev rule that specifically makes the user the owner of the device file using the OWNER udev key.

Added functionality to automatically add user's primary group to the udev rule in 069dd4a. Theoretically won't cover ever possible case, but the default functionality of useradd from the standard shadow-utils makes a unique primary GID for every user created.
