[sldev] Reviewing/Fixing the Particle System

[Strife Onizuka]

I looked at both past and present source with that in mind when I wrote my
last message. Regardless of the 1.14. changes, there hasn't ever been a
clamp on the system life. Adding one would break content.

http://svn.secondlife.com/trac/linden/browser/branches/2007/sculpties2 -
Current (1.16.0.?)
https://wiki.secondlife.com/wiki/Source_downloads#2007-Jan-08 - Past (
1.13.2.?)
