Feature request: Option regarding default behavior of seeding zites FOREVER

I keep deleting sites I visit only for once (seeing that I'm not interested in its content). I admit it, I'm kind of obsesive, I keep all my data quite tidied up.

I don't want to be asked every time I enter a site if I want to keep (like issue #492 ) this forever, but rather **I'd prefer to have a house cleaning built-in that erases zites I don't visit in N days**.

And I'd like to have some history of the websites I visit, with some information about the frequency of visits (how often I enter in a month). Using that information I would like deciding which zites I allocate more bandwith/disk usage.

This last point takes me to another one, I'd like to configure how much bandwidth/disk usage I donate to every zite. And, I'd like to see how much bandwidth/disk usage a zite has over all users-seeders.

I'm kind of thinking zeronet as a big new web. I love the project, I am looking forward to learn a lot about it. Thanks for the hard work!
