Template google analytics data

Browse Source 
Without this patch, the index.html contains google analytics at
all times, including for people self-hosting it.

This is a problem for privacy reasons, and only people wanting
to have analytics on their instances should be able to enable
them.

This fixes it by making sure the index.html page is templated
to sideload content from ANALYTICS_CODE_PATH (which itself is
also templated, for convenience).
