Add rain to indicate bad internet weather

[daonb]

What's missing? Please describe your flow and where this feature will help.

When a watchdog captures a timeout the Gate should change it's state to
"raining". The gate will go back to normal once any message is received from
the server.

Tasks

[] Add a weather WebGL layer to draw the rain
[] When it starts raining notify the user with info about the network he's
using
[] Add a timer in the form of increasing the rain until there's a flood and
the reset/close modal appears
