[Bf-compositor] Drivers inside node groups

[Lukas Tönne]

Drivers inside node groups are not supported atm unfortunately. This is a
deeply rooted problem with the dependency graph, which cannot handle
updates of anything other than object, scene, and armature datablocks
reliably. Even drivers in the top-level, non-group node trees (the main
compositor tree) only work because of hacks and only when the scene is
active iirc.

Sorry for the disappointment. We intend to fix the dependency graph asap,
but it can still take a while. Until then you could possibly work around it
with some explicit scripting and scene update handlers.
