Goaslicer Button Support 

Hi @pwhelan, 

This is just a merge of your goaslicer with my kill_buttons2 branch. 
It features a effect parameter button with a right click menu.
It includes also a steeper logarithmic scale over two decades (-40 dB) 

I would like to use the goaslicer, to verify that all parameter features are in place and my improve them for this Effect. 

What would be the ideal parameter setup for this? 

I am thinking to additional Tempo and Duty knobs and a Button for selecting the beat ratio 1/2/4/8/Free  

To be honest, I am currently a little bit lost what the current parameters are for. 
So I have set up a ooo calc table, showing the resulting gain. 
It looks a bit odd. So Would you mind to fix it? 
(See Google Drive) 

Thank you, 

Daniel
