Eldev 1.3

What's new in this release:

• New command doctor: pretty much like opinionated Eldev-based linter for your project and the current checkout rather than Elisp code.
• New command files, largely to simplify making sure that the project is properly configured.
• New command update-copyright in plugin maintainer.
• Emacs spawned by eldev emacs now has access to Eldev functions and project setup (files Eldev and Eldev-local) is executed in it too. This makes it easier to use Eldev for debugging output in interactive Emacs and also (temporarily) affect project code via configuration files.
• New function eldev-debug writes to Emacs’ stderr, making it especially useful in interactive Emacs (see the previous item).
• Eldev help screen has been reformatted for clarity.
• Eldev documentation has been moved to a separate site hosted on GitHub Pages.
