Added links

I added a link to the support page in the navbar. The only way to access it before was to click on the Donate button on the main page. I found it easier to have it in the navbar so it would be easier to donate, or find the github page for this project.

The second change is I changed the link to the tubalr reddit page from https to http. I got a warning from google chrome when clicking on the link with https, but changing it to http resolves that issue.
