getters for decibel and logarithmic volume (#1355)

Browse source 
* getters for decibel and logarithmic volume

I don't really understand where the conversion numbers come from but having this allows for an easy way to get the volume back based on what method you used to set it. I think the math is right, but yeah I've just used the conversion numbers from the other methods.

* fix trailing spaces
