Adding "favicons" to d.tube to properly display bookmarks on mobile devices

Components

This suggestion is about adding additional favicons to the d.tube server. These additional favicons are needed to properly display a bookmark of d.tube site when added to the home screen of a mobile phone or a tablet.

Proposal

Add the properly formatted "favicons" to the d.tube server. There is a need to add more different formats to accomodate different platforms (iOS Safari, Android Chrome, Windows 8 and 10, MacOS Safari).

A great tool that shows what files need to be added to the server can be found here: https://realfavicongenerator.net/favicon_checker?protocol=http&site=d.tube#.WrmAZ2aB3jA

Examples

Here is the current situation with d.tube. The screenshot shows that some favicons are missing:

As a reference the screenshot shows how the favicons are present on steemit.com:

Benefits

Favicon is a visual aspect of the site that is still very important and adds to the quality of the site. Right now d.tube lacks a favicon (app icon) for mobile devices.

Why favicon is important?

1. It helps in branding.
2. It adds to the recall value of the website.
3. When a bookmark for d.tube is added to the home screen on a mobile phone/tablet it is display as a nice icon that represents the brand. If there is no favicon a visual representation of the current content of the site (at the time of adding an icon to the home screen) is used which is not visualy appealing at all.
