Allow the on_blast API to pass an itemstack. 

If the node is special and has an on_blast() handler, we need
to call it instead of getting node drops manually. However, we
do want to know if drops should be added for the special nodes,
so we modify the on_blast() handler code to allow the nodedef
handlers to pass back itemstacks. This could be used by e.g.
the doors mod to drop door items after a blast.

Since this API is documented in lua_api.txt, a separate PR will
be incoming to update the on_blast() documentation.
