HTTP Error 404 for /favicon.ico

[lidel]

Directory listings are missing favicon definition, which makes browser to make request for implicit /favicon.ico which always fails.

To illustrate, opening https://bafybeiccfclkdtucu6y4yc5cpr6y3yuinr67svmii46v5cfcrkp47ihehy.ipfs.dweb.link/ produces two requests:

We could either add a favicon (would have to be inlined as dataurl to work in every context) or supress the request with:

<link rel="shortcut icon"type="image/x-icon" href="data:image/x-icon;,">

#36 should close this. Out for review.
