Update README.md
Replaced call to makeFullPathName to expandPath to take advantage of the expando functionality
When LifeMode was set to INFINITE (default), the check for Waitforparticles was skipped.
- Fix : moved check for LifeMode after the check for WaitforParticles

When calling ParticlePlayer.stop(), subsequent calls to ParticlePlayer.play() would not work.
- Fix : On ParticlePlayer.stop, particle emitters were paused individually, never unpaused later.
ParticleAsset & ParticleAssetEmitter.getSelectedField now returns a string representing the name of the selected field, as per original design.
Changed TamlWrite so that Data Keys are written out as children of the ParticleAssetEmitter's Fields, as originally designed.
