Fix/google font
requested to merge ghsc/contractors/olivier.combe_briebug.com/earthquake-latest-earthquakes:fix/google-font into master
Fixes #107 (closed)
I replaced Roboto by Merriweather (since we don't use Roboto). The link uses swap so it's already optimized (it will show the system font until the custom font is downloaded).
I replaced material icons by a custom font generated on https://icomoon.io/app/ with the svg icons from https://material.io/resources/icons/. Now it only weights ~4kb instead of 58 since it only contains the 5 icons that we use instead of all of the material icons.
