Reduces load_menus answer size by 32% (between 20kb and 200kb savings
for the initial loading of the backend, depending on the number of apps
installed). Support for SVG icons in the web client for menus/apps.
Reduced PNG icons for apps list (8 bits PNG instead of 24 as our icons
don't need more colors as they are flat designs)
