Added Override Notification Option to Weather Module

[NolanKingdon]

Fixes #3126

Added the option allowOverrideNotification to weather.js. This allows the module to receive the CURRENT_WEATHER_OVERRIDE notification. The expected payload for this notification is a full/partial weatherObject that is used to supplement/replace the existing weatherObject returned by whichever weather provider is in use.

No visual changes.
