This is a placeholder issue for reimplementing the site manifest and favicons functionality to use Hugo Pipes. It aims to address a number of discussions: #372, #682, #683, #711 and #713.

High level overview of the changes required:

• Remove all the static files
• Generate site manifest and favicons using Hugo Pipes
• Allow for favicons to be disabled
• Theme the favicons to match the selected colour scheme
• Better documentation around how this feature works
