Removed unused data type mapping function in RNA, this is now directly
refined through the type of the attribute/state.

More restructuring ... Putting state into attributes, otherwise mapping
between declared attributes in psys and attribute states becomes very
complicated.

Fix for paged buffer iterator, can be constructed for a buffer without
any pages.

Disabled strict alignment in paged buffer for now, this fails for vector
attributes, needs a nicer way to handle this.

Renamed RNA property of the particle system in the psys modifier.

Some renaming and DNA reorganization. Particle attributes now have a
descriptor as well as state data.

Removed deprecated DNA data inside #if 0 block, C preprocessor doesn't
work with makesdna.

Disabled some unused DNA code for nparticles.

Collection properties for actual data in particle buffers.

Setter callback for particle attribute data type. Currently just throws an assert failure, later on this should make sure the particle data is converted to the correct type (or simply make datatype read-only).

Basic properties for particle attribute descriptors. Uses a generic function to inject these properties using the nested 'desc' field.

Basic particle buffer implementation with RNA for adding and removing attributes.

Basic RNA for paged buffer and nparticle buffer.

Updated read/write code for paged buffer for the new layer/page structure.

Added missing DNA files to makesdna.

Added read/write code for NParticleSystemModifierData and NParticleBuffer.

Added missing draw function in the modifier panel.

Added applyModifier callback and AcceptsMesh flag so particle system can added on mesh objects. applyMesh is just a stub returning the unmodified mesh.

Renamed the modifier to NParticleSystem since it will also define some simulation modes in addition to the actual buffer.

Added a new modifier NParticleBuffer. This is just a thin wrapper around the NParticleBuffer struct to act as a particle container. Eventually could utilize a better object data system, for now this is ok.
