Fixing csp errors

[alexcolbeck1]

Description

In the console there were CSP errors such as:

Executing inline script violates the following Content Security Policy directive 'script-src 'self''. Either the 'unsafe-inline' keyword, a hash ('sha256-eGmUguHOQ+VD7QW20Cx2/mm+nZ5+iLoriiyS8I7V4pI='), or a nonce ('nonce-...') is required to enable inline execution. The action has been blocked.

So to fix this I'm moving inline javascript into an init.js file inside /assets/js
