Changed Favicon Generator Link

I used this site to generate the favicon for webdevchecklist.com. The
previous one (dynamicdrive) butchered the image and only included 2
sizes. X-Icon-Editor does 4. See the discussion at: http://www.jonathantneal.com/blog/understand-the-favicon/ for more information.
Updated Favicon

Updated the default favicon. Added Windows 8 Tile Icon and iOS Home Page
icons.
