Add an homescreen icon for iOS devices #18
Description
I personally use Detexify on my iPad, so I added a shortcut to my homescreen, but it doesn't have an icon. (It defaults to a very small site preview) This isn't really a big problem, but it would be a very small nice to have.
If you have a bigger version of the favicon, we could set it as an homescreen icon. (Or something else)
Homescreen icons can be added by adding the following line to the <head> section of the document:
<link rel="apple-touch-icon" href="/path/to/icon/apple-touch-icon.png">
