Added a basic favicon in the various formats.

• The image is not optimal, but it will do for now.
• Note: favicons dot not show in Safari tabs, but do show in history

Thanks, Dolf!

Did you draw this entirely yourself, or did you compose it from other sources? If the latter, are there licensing details we should note in some fashion? E.g., my understanding is that CC BY is a common license for image assets; I think we'd need to add something to LICENSE.

The image is a composition (Photoshop) of two others:

• The moon against the ridge was taken from https://twitter.com/fire_party and does not appear to have any copyright notice with it. I consider it in the public domain
• The camera came from a product image on Amazon (I think), so should not be a problem either.

So I think CC BY would be appropriate. If we ever have something professionally designed that might be different.

Shoot. My understanding is that images are copyrighted by default rather than in the public domain. And I wouldn't be surprised if a security camera company in particular were upset about using their image in our NVR; it could be taken as an endorsement. Sorry. We can't use either of those images.

Maybe it's better to use something more abstract/icon-like anyway; at least when used as a Chrome tab icon, you really can't make out much detail.

OK, so I updated my PR branch with a CC0 based image.
