It is ridiculous detail but could be life saver debugging.

Could later work on pb toStringing so it doesn't dump it all... just start of String and a
length instead but this should be good for now.

Remove Objects class since no longer used.

> The places where the type of objects are inspected need to be updated to take into consideration
PB types. I have noticed Objects.describeQuantity being used, and the private WritableRpcEngine.Server.logResponse
method also needs updating (in the PB world, all information about operations/tablenames is
contained in one PB argument).
