Jacques Lucke 0247ee5f53 Simulations: Add simulation node tree type 
This implements a new builtin node tree type called `SimulationNodeTree`.
It is not yet embedded in the `Simulation` data block.

The node tree will initially be used for the new particle nodes system.

When the cmake option `WITH_NEW_SIMULATION_TYPE` is enabled, a new
`Simulation Editor` is shown in the editors menu (which is just a node editor).

This patch does not add entries to the Add Node menu, so it is empty.
