Server-authoritative weather needs implementation

[Stormeus]

The following functions are broken due to the lack of implementation of the server's authoritative weather controller in Squirrel:

• GetWeatherLock

• SetWeatherLock

• GetWeatherRate

• SetWeatherRate

The Squirrel plugin or a third party plugin must thus be able to control the weather. This may be moved to a third party plugin that uses the implemented module hooks to register functions to Squirrel, which can then be ported to Pawn and Python if and when made available.

Not fixing; scripters can implement weather themselves
