Melanie Thielker e526e8c5e2 Fix the long-standing bug that object permissions set in inventory were lost 
NOTE: Items rezzed by users using 0.8 or older will still exhibit broken
behaviour. Until 0.8 becomes end of life, this fix will not produce
dependable results on grids with mixed versions. Grids based on 0.9 will
now work properly.
