Configuring web application icon

[via-justa]

When saving a link to packstack.io to home on iOS the site logo is missing.
Adding support for that require only adding apple-touch-icon.png on the site root folder as described here

I think it's a fast win that should not be hard to implement and would be a very nice addition.
