Subject: [PATCH 1/3] Checking internet connection & preload requirement

Modules which doesn't require preloading can be provided with data: {preload: false} in the route.
Internet connection checked before preloading. If the connection is on a 2G network or if the data saver is enabled, preloading will not be done.
