Restricting contributions on ari-web

Hello world,

Due to changed Netlify plans I will be restricting contributions on all of my sites, if you want to add something make an issue and I will add it crediting you, until the plans change or I will be able to afford $40 per contributor I will keep pull requests closed

And as it comes to the files site I will restrct it to private usage mainly, but don't worry, if you want to I can still upload files on there for you but the process will be much slower

I am sorry that I have to do this but I simply cannot afford that much per contributor, I will revert the change as soon as I can
