Google Code-in

Some of the sample platform's website libraries which we are using are somewhat outdated. We should investigate if we can upgrade them without breaking anything.

This task is to upgrade Font Awesome (currently 4.5.0, 4.7.0 is available), and open a Pull Request with the modified files. You should also check if any incompatibilities were introduced between the currently used version and the newly installed one.
