Fix frontpage avatars ()
The frontpage uses a rather strange method to obtain the commit's avatar
which I've overlooked earlier. I don't exactly understand how it works
but this change fixes the wrong default avatars by using the function
that was in previous use.

Also introduced a few constants for size an size increase factor.
