Buzzer sounds

[skrubis]

Create a bunch of sounds for various emotions:
1)soft attention - upon change of environment (lights on)
2)attention - upon need to open a window
3)bad - if someone blows a co2 canister at it
4)happy - when air quality returns to acceptable levels
5) (?) if it gets really cold?

Some randomization/variance in these sounds is encouraged to not be too repetitive.
