Better Shell troch vantaboard

Finds commands on a page and makes the prefix non-selectable so you don't accidentally copy it and adds a copy to clipboard button.
This extension finds <pre> tags and looks for shell commands and makes them non-selectable so that when you are copying them to your terminal, you don't have to worry about removing them from each line. Furthermore, it adds a copy to clipboard button to every <pre> tag as well. Check out the GitHub page for the roadmap, and feel free to shoot me an email at brightenqtompkins@gmail.com if there is a missing feature that you would like added. https://github.com/vantaboard/better-shell
