Update docs for 1.2.0

[brianbunke]

Re-generated the documentation after bumping the master branch to version 1.2.0.

The basic process here:

1. Run PowerShell as admin
2. .\build.ps1 -TaskList InstallPrerequisites
   • Installs Chocolatey, Calibre, NodeJS, Node modules Gitbook-CLI & Gitbook-Summary
3. .\build.ps1 -TaskList GenerateSite
   • Also runs task Compile as a prereq, which creates folder \compiled_docs
4. Everything in the new \public folder is the entirety of your new gh-pages branch

Once merged, this will be live at https://wahlnetwork.github.io/Vester
