Problem/Motivation
The default favicon in /misc/favicon.ico is 16x16 and looks awful on retina screens.
Proposed resolution
Replace misc/favicon.ico with a retina version. See https://github.com/audreyr/favicon-cheat-sheet for comprehensive information but in this case we are merely trying to fix the basic icon.
Remaining tasks
- Create a 32x32 favicon.
- Test on various devices.
- Backport.
User interface changes
Non-pixelated favicons should appear on browser tabs.

API changes
Any derived themes that may somehow depend on a 16x16 icon could have an issue.
