Bug fixes

Hi,

Have done the following as requested:

1. Authors and dates now updating on homepage blog panel
2. Replaced icon in Sandro book section
3. Resized feature image (reduced). Added media query to mobile. (Hoping these two things solve the Iphone bug).  Added shadow to white text in feature image.

Tested using the Chrome mobile emulator but won't know if the iphone bug is fixed until you push to live.
