Set up continuous deployment (#70)

* Add build step to circleci config

* Add deploy job to circleci

* Configure test → build → deploy as a cascade and ensure `public` exists when building

* Add deploy key

* Deploy only on master

* Remove ssh keys from build step

* Remove travis-ci

* Move build-report into task and update README.md

 ### Editor integration
 
-Integrating shadow-cljs with your editor helps tremendously with development. After having run `npm run dev` as described above you can connect to the REPL and get features like in-editor code execution and code completion / documentation lookup. For further information see [this part of the shadow-cljs user guide](https://shadow-cljs.github.io/docs/UsersGuide.html#_editor_integration), which contains instructions for Emacs, Atom, VSCode and other editors. Make sure to open `localhost:8080` in the browser to execute ClojureScript code.

For further information see [this part of the shadow-cljs user guide](https://shadow-cljs.github.io/docs/UsersGuide.html#_editor_integration). Recommended editors and plugins are Calva for VSCode and CIDER for Emacs (comes with Spacemacs). Make sure to open `localhost:8080` in the browser after starting the `dev:cljs` task to execute ClojureScript code in a live REPL.

+There is continuous deployment set up on [circleci](https://circleci.com/gh/heyarne/airsonic-ui) that builds and deploys to `gh-pages` after a commit to the `master` branch.
+
 **Note:** If you have a continuous build running and run `npm run build` or `npm run deploy`, it will delete the compiled tests, causing the continuous tests to not run anymore. This can be fixed by running `npm test` again.
 
 All build artifacts land in `/public`. Don't change anything in there as changes will be overwritten.
