Automation handling

[raevol]

Need to work out interface for describing automatible "parameters",
which is tightly coupled to the effect plugins, the design of the render nodes and the design of the GUI/Proc interface. Can't be done isolated from those areas, and thus is a general blocker at the moment (9/08)

But, on the contrary, an general framework how the automation
implementation works could be done right now and almost completely
independent of the rest.

• flesh out the ParamProvider interface
• create several implementations
  • based on a bezier curve
  • based on interpolation of a given data set
  • based on a mathematical function, e.g. sine oscilation
• solve the problem how state data required by the implementation can be attached and associated with the render processes (by using data frames which can be managed by the cache)

The topic remains important, but can't be adressed by the core developers currently.
