Linting v2

[jfhbrook]

As promised - #94 with the alias removed. To recap, this:

• Adds simple directions for using PSScriptAnalyzer for linting
• Changes a variable name so as to not shadow the automatic $args variable inside a function
• Adds ShouldProcess support to functions with names that start with Set

I decided to punt on updating the tests to use the latest Pester - this work should probably still be done, but I'd rather not send a PR that half-asses it.

Drat, looks like Pester 5 has quite a lot of changes in it that are causing the build to fail.

I'm going to make a change where I pin Pester to v4 for the time being so the PR can be reviewed and separately Pester 5 can be investigated.

I've just updated the tests to use Pester 5 and merged that into your branch.
