Fontawesome icons for Follow

Hi! I created a sandbox module to expand Follow funcionality https://www.drupal.org/sandbox/sergiocarracedo/2635820 → .

This module provides some new funcionalities to Follow:

• Use Fontawesome for social icons (Some networks are removed because fontawesome haven't icon for that)
• Add Github as new network
• Allow to set email as a social network

This module need improves, for example a better place to add CSS, but is fully functional
