Add settings to enable/disable (un)wanted features

[shawninder]

Be they a battery drain, useless bandwidth consumption or simply eye sores, some users may want to enable/disable the various features offered by this app:

• map in the background
• background pattern
  -certain metrics
  • feels like
  • humidity
  • probability of precipitation (pop) Where is this even at the moment?
  • wind speeds
• 3-day forecast
• 7-day forecast
• Iconography
• language switcher

These could be simple toggles, but they should be remembered between sessions and they should provide the ability to avoid downloading what isn't needed, e.g. If the map is turned off, no use downloading the client!

a.k.a display: none is not enough.

Also, check for any transitions or animations which could be turned off with the prefers-reduced-motion browser setting.

The settings will probably have to be saved in a cookie, which introduces the need for a cookie bar…
