[Bf-compositor] Use Nodes button

[Jeroen Bakker]

Hi all,

It is also a bit of legacy. First time clicking on use nodes will create 
an initial composite node setup. It is because the other node tree types 
(material/texture) can have multiple trees, but there is only one 
composite tree per scene. The button is the same as the '+' button on 
the other node trees types. The "Compositing" setting is introduced to 
disable/enable the compositing step in the pipeline.
