More interaction with objects/effects with weather

[illyaine]

The weather should get more interaction accordingly, that when raindrops hit objects, that they bounce off, move better with the wind and much more. Of course, also that the wind reacts to objects, etc.

Bouncing raindrops off objects will be very costly operation, and bouncing off room geometry already affects performance. So I would abstain from that and maybe only produce fake bouncing which is not linked with real raindrop physics.
