Add Licence about site

We should get this done ASAP - the more contributors we have the harder it would be to switch the license to MIT / Apache, especially considering that there are outside contributors (including me) who have contributed to this.

I got a reply back from @dragostis back in November that he'd try to add one soon, and that he didn't previously add a license to the original code, because he didn't anticipate the project would become popular.
Anyway, I just sent him a reminder and we can give it a few days (if there's no reply, we can go with the same license as on the main pest repo in the meantime).

got a reply from @dragostis:

Hi Tomas,

Feel free to do use the same license. I won't have time these days to fix the domain issue.

Dragoș

so I'll just add the main pest repo's license

I'd assume so, better for @dragostis to clarify

Once he adds the license, I think we need confirmation from all of the contributors that they don't mind licensing their contributions in that license (when no license exists, the inbound=outbound rule doesn't apply) - so once dragostis adds the license, we need some form of approval from everyone who made non-deleted changes.
