The following nodes work now (although things can still be improved of course):
Particle Birth Event, Praticle Time Step Event, Set Particle Attribute and Execute Condition.
Multiple Set Particle Attribute nodes can be chained using the "Execute" sockets.
They will be executed from left to right.
This operator automates the following steps:
1. Create a point cloud object.
2. Create a simulation data block.
3. Add a small particle simulation to the node tree.
4. Add a Simulation modifier to the point cloud object.
5. Reference the particle simulation from the modifier.
You have to go back to frame 1 to start the simulation.
The simulation is not yet cached and cannot be rendered.
The bounding box of the point cloud object is enabled for now,
because otherwise it is hard to select the object.
This commit adds the initial set of particles nodes. These are fairly
low level and are expected to be put into groups that we ship with Blender.
See D7384 for a description of the individual nodes.

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.
