[Opensim-dev] touch_start in linked prims

[krtaylor]

When I first implemented/fixed touch_start for linked groups, I thought 
just as you did Will.  But Melanie showed me the error of my ways (and 
supplied a patch too).   ;-)   I went back and did a bunch of testing 
and I believe that we are handling touch_start correctly now...

In Second Life, this doesn't happen as only the root prim with the touch_start handler is hot.
