Improved zaproxy.org integration

[psiinon]

Just changing the ZAP icon in the top left to link to the top level of zaproxy.org would help. Any other suggestions?

The first link is referring to: https://owasp.org/www-project-zap/ , should we refactor it to ZAP as well?

Yes (we also need to update that in the readme), the link to the getting started guide could be changed to the online page https://www.zaproxy.org/getting-started/.

Closing, done with #26 and #27.
