first cut at a GridInfo plugin (mantis #1825). Currently just spits

out everything in the [GridInfo] section :-D Also, not yet LLSD but
XmlRpc, LLSD via GET will follow. OpenSim.ini.example contains sample
values and explanation. Oh, and default values provided are 

       platform: OpenSim
       mode: standalone | grid

have fun.
