github PR #787 - segfault for wizterrain wish

Browse Source 
Pull request from entrez:  the change to show the result of a wish in
its gamelog/livelog event resulted in a segfault if that result was
&zeroobj.  It occurs for wizard mode wishes producing terrain changes
instead of objects.

Closes #787
