Cryogen Blog template with staging and Practicalli theme

[practicalli-johnny]

Create a Cryogen template to create a new blog project that includes

• publishing pull requests to a staging blog
  • modified src.cryogen.core/-main to take a config file via the command line
  • GitHub workflow to publish to a separate staging repository
• include practicalli theme
• option to select the default theme ??

Cryogen includes a deps-new template that simply copies from the Leiningen template

Code modifications

Allow a configuration file to be passed to the -main function, which is used to build and publish the Cryogen blog

TODO: refactor the code so that the zero argument branch calls the config-file branch, e.g.

(defn -main
  "Start Cryogen with optional configuration file"
  ([]
   (-main "content/config.edn") ;; TODO: test this approach works and path to config file is correct
   ;; (load-plugins)
   ;; (compile-assets-timed )
   ;; (System/exit 0))
  ([config-file]
   (load-plugins)

   ;; Would edn reader be better than read-string?
   (compile-assets-timed (read-string (slurp config-file)))
   (System/exit 0)))
