* Particle meshes now call updateCounts() when number of particles changes. This might fix native crashes in some cases.

Browse Source 
* Removed completely useless merge sort on the entire particle array from ParticleTriMesh ...
 * Added a small note in the javadoc of VertexBuffer.updateData() regarding bizarre issues
